Renamed [class_]drawpanel_gal.[cpp|h] to [class_]draw_panel_gal.[cpp|h] to follow current naming scheme.

Minor fixes for Windows: move resources from dso to .exe, to have the application icon in executable, and therefore shown in shortcuts.
pcb_calculator: minor coding style fix.

CvPcb: Fix crashes when starting cvPcb (could be Windows Specific) and after closing the footprint viewer.

!   The initial testing of this commit should be done using a Debug build so that
    all the wxASSERT()s are enabled.  Also, be sure and keep enabled the
    USE_KIWAY_DLLs option.  The tree won't likely build without it.  Turning it
    off is senseless anyways.  If you want stable code, go back to a prior version,
    the one tagged with "stable".

*   Relocate all functionality out of the wxApp derivative into more finely
    targeted purposes:
    a) DLL/DSO specific
    b) PROJECT specific
    c) EXE or process specific
    d) configuration file specific data
    e) configuration file manipulations functions.

    All of this functionality was blended into an extremely large wxApp derivative
    and that was incompatible with the desire to support multiple concurrently
    loaded DLL/DSO's ("KIFACE")s and multiple concurrently open projects.
    An amazing amount of organization come from simply sorting each bit of
    functionality into the proper box.

*   Switch to wxConfigBase from wxConfig everywhere except instantiation.
*   Add classes KIWAY, KIFACE, KIFACE_I, SEARCH_STACK, PGM_BASE, PGM_KICAD,
    PGM_SINGLE_TOP,
*   Remove "Return" prefix on many function names.
*   Remove obvious comments from CMakeLists.txt files, and from else() and endif()s.
*   Fix building boost for use in a DSO on linux.
*   Remove some of the assumptions in the CMakeLists.txt files that windows had
    to be the host platform when building windows binaries.
*   Reduce the number of wxStrings being constructed at program load time via
    static construction.
*   Pass wxConfigBase* to all SaveSettings() and LoadSettings() functions so that
    these functions are useful even when the wxConfigBase comes from another
    source, as is the case in the KICAD_MANAGER_FRAME.
*   Move the setting of the KIPRJMOD environment variable into class PROJECT,
    so that it can be moved into a project variable soon, and out of FP_LIB_TABLE.
*   Add the KIWAY_PLAYER which is associated with a particular PROJECT, and all
    its child wxFrames and wxDialogs now have a Kiway() member function which
    returns a KIWAY& that that window tree branch is in support of.  This is like
    wxWindows DNA in that child windows get this member with proper value at time
    of construction.
*   Anticipate some of the needs for milestones B) and C) and make code
    adjustments now in an effort to reduce work in those milestones.
*   No testing has been done for python scripting, since milestone C) has that
    being largely reworked and re-thought-out.

Commit patch about  cvpcb, pcbnew and layout editor menu items, with 3 menu labels modified in Eeschema.

Add missing calls to Show( false ) to some main frames (Kicad, eeschema, gerbview), to force config saving when closing these windows.
Code cleanup and minor coding style fixes  in footprint_wizard_frame

Add EDA_BASE_FRAME::Show() and call SaveSettings() only from there for all derived wxFrames.  Remove calls to SaveSettings() elsewhere.

Added PICKED_ITEMS_LIST::FindItem().

move ${Boost_LIBRARIES} into cvpcb, pcbnew, _pcbnew and out of github, because worker threads used regardless of github

   To use multiple working threads.  This entailed adding KiCad typedefs:
*) Add typedefs for MUTEX and MUTLOCK which mask the actual choices for the project.
*) Add FOOTPRINT_LIST::DisplayErrors( wxWindow* ) which is a single strategy for
   showing aggregated load errors.  Although what's there is only scaffolding
   and needs a volunteer who knows HTML pretty well.
*) Ensure all callers of ReadFootprintFiles() use the new DisplayErrors() function.   
*) Push utf8.cpp and utf8.h into common library for open use.

* Pcbnew: catch exceptions when saving changes to footprint library table.
* Pcbnew: update footprint viewer library list if open when footprint library
  table changes.
* CvPcb: update library list when footprint library table changes.
* Minor coding policy fixes.

All: under mingw32+msys: fix an issue when using Cmake version >= 2.8.5 which uses by default a response file.
This response file is not expanded under mingw3 2 (mingw/gcc bug?), and the list of include paths, found in this file, is not taken in account.
Now, under mingw32+msys, when not cross-compiling, the response file is disabled.
Cvpcb, Pcbnew: fix a list of libs  which should be added only when cross-compiling:
Previously, they were always added, which creates an issue with mingw/msy/ gcc  2.8.
Now they are added only when cross-compiling (this issue was noticeable only with msys+mingw version  2.8)

<%s> being replaced with '%s' because the former in invisible in html panels.
Cure some compiler warnings.

* Create a generic yes/no/cancel dialog from DIALOG_EXIT.
* Make DIALOG_EXIT return wxID_YES instead of wxID_OK so it is consistent
  with the standard message dialogs.
* Add missing license to confirm.h and confirm.cpp.
* Change Eeschema message dialog when loading a schematic if the current
  schematic is modified to be more consistent with the exit dialog.
* Change Pcbnew message dialog when loading a board if the current board
  is modified to be more consistent with the exit dialog.
* Remove some Eeschema block debug logging code left over from my last
  commit.

*) Set environment variable KISYSMOD before loading FP_LIB_TABLE so that
   FP_LIB_TABLE::ROW::SetFullURI() can do substitution up front.
*) De-emphasize the lib path in some of the footprint frames but keep it
   so the footprint editor can export a current library to another.
   You can even export a GITHUB library to a pretty library for local 
   installation.
*) Start the PLUGIN options editor.
*) Enhance cursor positioning in DIALOG_FP_LIB_TABLE.

* Add save table and set project path environment variable code to
  FP_LIB_TABLE object.
* Add code to Pcbnew and CvPcb to set project path environment variable.
* Create empty footprint table in Pcbnew when new board created.
* Save current project specific footprint library table to path on file save
  as or empty project path.
* Fix a bug in Pcbnew in file save function that would silently overwrite
  an existing board file.
* Disable selecting the current library in the module editor when there are
  no libraries defined.
* Catch exceptions and report errors when writing footprint library tables.
* Fix Boost build CMakeFile to fix bug when bootstrapping a Boost build in
  MSys.

Move specctra.cpp, specctra_import.cpp and specctra_keywords.cpp compilation to pcbcommon lib because they containt functions used by the 3D viewer in Cvpcb and Pcbnew.

3D board display: better rendering of the board: the board polygon outlines (generated by the specctra function) is now used to create the 3D body of the board.

* Remove fp_lib token from board and s-expr netlist file format.
* Fix a bunch of Doxygen warnings.
* Remove some extra debug log messages.
