Kicad manager: fix a recent bug: project tree not updated when kicad is launched by a command line with a project name to open.
pcbnew: export vrml:
* move dialog functions in a new file: dialog_export_vrml.cpp.
* fix coding style issues
* patch add from cirilo Bernardo.

Fixes a bug in the template file copying mechanism. The previous code failed to honour sub-directorys and flattened the whole tree whilst copying files.
I have fixed this so that sub-directories that are not the meta directory will get copied verbatim into the new project directory.

Kicad manager: first use of wxFileSystemWatcher (only with wxWidgets >= 2.9.2) to monitor files list.

Because now there are 2 formats, board backup files extensions are .brd-bak or .kicad_pcb-bak instead of the old .000 extension, depending on the initial file format.

Add KiCadPcbFileExt global.

fctsys.h: remove useless define.
Fix minor issues and add minor enhancements.

Kicad manager: project_template.cpp: accepts  lower and upper case HTML keywords (compatibility with libreoffice)

All: remove macros  MAX, MIN, ABS from macros.h and replace these macros by std::max, std::min and std::abs (mainly found in old code).

Other minor fixes.

Code cleaning, minor fixes and minor coding style fixes. wxWidgets 2.9.4 compatibility fix( deprecated function MakeModal )

Kicad manager: shows now svg files in tree files.
Pcbnew: fix incorrect printing (board out of page) when creating drill map in postscript format ( noticeable mainly for small boards)

* Add s-expression file parser object and keyword files.
* Fix minor issues with s-expression file formatting.
* Fix a minor bug the zone container fill state parsing in the legacy plugin.
* Move EDA_TEXT visibility definition to eda_text.h.
* Add minor BOARD_ITEM object improvements to support s-expression file
  parser.

Kicad manager: code cleaning. Dead code removed and minor fixes. support of new .kicad_brd extension.

* Move EDA_TEXT object into separate header and source file.
* Compile EDA_TEXT class separately for BOARD_ITEM and SCH_ITEM units.
* Compile PAGE_INFO  class separately for BOARD_ITEM and SCH_ITEM units.
* Minor formatting tweaks to Pcbnew s-expression file.
* Move internal unit formatting functions into BOARD_ITEM and SCH_ITEM.

Enhancements in AddMenuItem (that accepts now a menu type)
Partial use of the Edwin van den Oetelaar's patch (patch not fully working or correct)

* Add s-expression Format() function to all objects derived from
  BOARD_ITEM.
* Add s-expression Format() function to base objects as required.
* Add functions to convert coordinates from base internal units
  (nanometers) to millimeter string for writing to s-expression
  file.
* Add temporary dummy conversion functions to prevent link errors
  until schematic and board object and action code can be separated
  into DSO/DLL.
* Add CMake build option to build Pcbnew with nanometer internal
  units.

Code cleaning and other minor fixes.

* EDA_DRAW_FRAME completely encapsulated except for DrawFrame member.
* Moved members specific to Pcbnew from EDA_DRAW_FRAME to PCB_BASE_FRAME
  or PCB_EDIT_FRAME as appropriate.
* Replace EDA_TOOLBAR with wxAuiToolBar as EDA_TOOL bar provided no
  additional functionality and made code less readable.
* Remove EDA_TOOLBAR class definition from wxstruct.h and delete file
  wineda_toolbar.cpp.
* Rename tool bar members to something more descriptive since the
  horizontal and vertical references wont mean anything once the
  tool bars are movable.
* Lots of dead code removal.

* Fixed bug on Windows that prevented the menu short cuts from working
  properly.
* Fix duplicate menu short cut keys in KiCad, Pcbnew, and Eeschema.
* Add menu short cuts for all possible menu entries.

* Correct all user strings and comments for the correct capitalization of
  application names according to JP.  They are KiCad, Pcbnew, CvPcb,
  Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
