* Use "Close" in the file menu of every main frame window instead of the
  mismatch of the terms "Close", "Exit", and "Quit".
* Change the terminology in the Pcbnew graphic text edit dialog to match the
  module text edit dialog.
* Improve the layout of the Pcbnew graphic text dialog.
* Fix some wxPrintf parameter type assertions for 64 bit time_t.
* Fix all (at least I think I got all of them) duplicate menu accelerator
  characters.

Previously, only the lib named "power" was used (and therefore power parts defined in other libs not shown).
Now, all power parts can be loaded from any library.
Also, when loading power parts from the chose component dialog or the lib viewer, libs and parts are filtered:  only power parts and libs containing power parts are listed.
Hotkeys: move a few global strings in the files where ther are actually used (and make them local.) and code cleaning.
Fix a few other minor issues.

* Create new dialog to edit environment variables.
* Add helper class ENV_VAR_ITEM to manage environment variable values and
  if they were defined externally.
* A path configuration dialog access to KiCad, CvPcb, Pcbnew, and Footprint Editor
  window menus.
* Add validator for environment variables.

Very minor fixes: 3D viewer: remove artifacts with NPTH pads having the save size as their hole. Kicad: remove duplicate submenu in menubar. remove a minor coverity warning

Make hotkey string info translatable in dialogs. These strings are now prefixed by _HKI , which can be used by translation tools to extract them.

* Add wxTAB_TRAVERSAL to TREE_PROJECT_FRAME ctor.
* Please note that there is still a focus issue when closing a child window (at least on
  windows) that prevents this from being an ideal solution.
* Minor code cleaning.

* Fix default KISYSMOD/KISYS3DMOD (#ifdef typo) for OSX builds.
* Remove setting KIGITHUB from kicad/pcbnew Info.plist in favor of hardcoded default
  setting for OSX builds.
* Remove now unneeded Set3DShapesDefaultPath() and other small things.

Minor and very minors fixes: move -DKICAD_USE_WEBKIT definition to the main CMakeLists.txt. Remove duplicate semi-colon at end of some lines.

- Remove a local patch that was added to trunk as wxwidgets-3.0.0_macosx_scrolledwindow.patch

Fix many doxygen warnings (due to missing info, old comments, typo ...) when building the doxygen doc.

Kicad manager, Gerbview: When running Gerbview from Kicad manger, set the Gerbview  CWD to the current project directory.
Therefore, when trying to open Gerber files, the default directory is now thecurrent project directory.
(fix Bug #1380088 )

Kicad manager: fix Bug #1385953 (unable to open .PDF files with spaces in name/path when using default PDF browser).
Fix also an issue when selecting preferred browser.

eeschema: fix Bug #1385789 (eeschema segfaults, when editing a new field). Fix an other minor bug in Footprint editor.

python scripting: refinement for UTF8 class (from Miguel Ángel Ajo Pelayo) add __str__  method, usefull to print a UTF8 string.
Kicad manager: fix issues in file watcher: changes (adding/removing files)  in project folder not seen by Kicad manager (perhaps due to changes in internal wxWidgets code between 2.9.5 and 3.0).

Archive function now recurses project sub directories.

* Fix creation of single app bundle with respect to scripting support.
* Cleanup scripting search paths for OSX.
* Fix some small CMake bugs from previous OSX build change.
* Optimize bundle file structure to be consistent with Apple specs.
* Add helper script for compiling wxWidgets and wxPython
* Update OSX build instructions.

* Compile all binaries into a single application bundle.
* Use CMake BundleUtilities to make application bundle relocatable.
* Restructure build output to directly create an image file.
* Fix default search paths.
* Set KIGITHUB environment variable.
* Added patch to fix wxWidgets so names for OSX.

Kicad manager: fix an issue when starting eeschema from its button: if the library editor was previously running, and if the quasimodal field editor dialog was called, eeschema dis not start on Windows, or started but dis not load the schematic project on Linux.
Enhancement: if a tool is running but is iconized, clicking on its button bring the window on screen.

Eeschema: remove the compil option KICAD_KEEPCASE. Eeschema is now always case sensitive when seraching components in libs.
However to be compatible with old versions of Eeschema, when a search in library fails, a case insensitive search is made.
Therefore, this version should be compatible with sch files created by previous Eeschema versions compiled with KICAD_KEEPCASE = OFF

Eeschema: schematic libraries in a sub path of standard libraries paths are now better handled.

Kicad:  more understandable dialog when creating a project from template. Fix also a bug when copying and renaming template files.
Pcbnew: dialog to create new .pretty lib: fix an issue which prevent to open a full disk directory (at least on Windows)

all: fix Bug #1361233 (a template.pro copy file overwrite silently the current project file when a group info is not found, which is a bug, because this group could be just a new group, not yet used)

Add patch from Mario Luzeiro to 3D viewer. Fix a serious issue due to duplicate ID used in menus and toolbars between sub-applications, related to wxUpdateUIEvent events loop.
wxUpdateUIEvent events can be sent to parent frames, when opening a menu in a child frame, if parent and child frame share same ID fro menuitems (or tools)
The wrong menuitem can be used in some cases ( because there are more than one menuitem with the same identifier), by a wxUpdateUIEvent event function run in a parent frame.

  *) When kicad.exe closes a project, close any open KIFACEs so that they cannot
     get disassociated from their true PROJECT.
  *) Allow loading eeschema library editor from kicad.exe
  *) Allow loading pcbnew library editor from kicad.exe
  *) Rename LIB_COMPONENT to LIB_PART.
  *) Add class PART_LIBS, and PART_LIB.
  *) Make PART_LIBS non-global, i.e. PROJECT specific.
  *) Implement "data on demand" for PART_LIBS
  *) Implement "data on demand" for schematic SEARCH_STACK.
  *) Use RSTRINGs to retain eeschema editor's notion of last library and part being edited.
  *) Get rid of library search on every SCH_COMPONENT::Draw() call, instead use
     a weak pointer.
  *) Remove all chdir() calls so projects don't need to be CWD.
  *) Romove APPEND support from OpenProjectFiles().
  *) Make OpenProjectFiles() robust, even for creating new projects.
  *) Load EESCHEMA colors in the KIWAY::OnKiwayStart() rather in window open,
     and save them in the .eeschema config file, not in the project file.
  *) Fix bug with wxDir() while accessing protected dirs in kicad.exe
  *) Consolidate template copying into PROJECT class, not in kicad.exe source.
  *) Generally untangle eeschema, making its libraries not global but rather
     held in the PROJECT.

and forces absolute path.

*) re-enable the MacOpen() support.
*) fix path truncation bug.
*) open *.kicad_pcb and *.sch files in the same process if they are part of the 
   the currently open project, even from the tree view.

switch back to original sexpr usage of PTREE, add new DSNLEXER constructor, enforce accessors in kicad.exe
