Write parser and formatter for options.  Write dialog verification used before saving
FP_LIB_TABLEs, triggered from OK button in table editor.
Switch PROPERTY's value column to std::string from wxString.
Add event handler to fp lib table dialog for upcoming options dialog.

* When loading footprint do not retest every footprint in cache.  Only test
  the footprint being loaded.  Fixes long load times on libraries with a lot
  of parts.
* Fix footprint name bug where file extension was added to the end of the
  footprint name.
* Fix bug in path equivalence test due to Posix path separators in footprint
  library table.  Convert paths to native separator before comparison.
* Fix a bug in FOOTPRINT_VIEWER_FRAME::OnActivate() which cause the footprint
  list to always get reloaded when using footprint library tables.
* Remove some unnecessary debugging messages.
* Add a few Doxygen comments to FP_CACHE in kicad_plugin.cpp.

Enhance IO_MGR::GuessPluginTypeFromLibPath() to support the GITHUB plugin.
Build boost with -fPIC on Linux unconditionally, in preparation for
DLL/DSO build of kicad.
Add python script to test back to back reads of GITHUB plugin.

* Make footprint editor work properly with library table.
* Fix bug in Eagle plugin when comparing file timestamps.
* Fix bug in footprint viewer when error occur loading footprints from
  the selected library.
* Fix error message display by in footprint viewer on library load error.

Other platforms to follow as volunteers test support and get openssl in 
place.

* Make footprint viewer work properly with library table.
* Fix bug in Eagle plugin when enumerating footprints.
* Add missing P-CAD plugin from footprint library table editing dialog.
* Fix bug in FOOTPRINT_INFO::LoadLibraries when error occur loading footprints
  from libraries.

BUILD_GITHUB_PLUGIN will build GITHUB_PLUGIN on Linux now.  Don't know if the parser works yet, but the FootprintEnumerate() function worked in testing.

1. block created from-left-to-right selects only 100%inside selection objects (as it now does)
2.block created from-right-to-left selects all overlapping objects inside selection
From the patch sent by mathieulj (mathieulj), and some fixes and code cleaning.

pcbnew.py + doxygen-xml files, and build .i files with docstrings,
those .i files are included back again to build a pcbnew.py with
extended documentation from C++, finally we take the final pcbnew.py
to build the doxygen-python documentation

Pcbnew: better dialogs to select the active layer or a layer pair. Add an option (hotkey+popup menu) to place a via and select the new active layer
(useful for boards having more than 2 layers)
Eeschema:fix compatibility with old schematic files, when they  contain ERC markers.
Pcbnew: better test for allowed layers when creating/editing Dimensions and some other Graphic items
Drc:  fix comments and messages for some drc tests.
Fix minor bugs in cleanup dialog options and plot solder mask function (thanks to Lorenzo to locate these bugs)

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

* Add code to CvPcb to handle assigning component footprints from the
  footprint library table instead of the search path method.
* Add code to CvPcb to allow editing of the footprint library table.
* CvPcb footprint and component panes display fully qualified FPID names.
* Make CvPcb library pane display footprint library table nicknames instead
  of library file names.
* Add code to FP_LIB_TABLE object to test the paths in the table against the
  list of libraries loaded from the project file.
* Add code to FP_LIB_TABLE to convert assigned footprints in a NETLIST from
  legacy format to footprint library table format.
* Split out COMPONENT_NET, COMPONENT, and NETLIST objects from netlist_reader
  files and create new pcb_netlist files.
* Fix minor wxListView scroll bar sizing issues.
* Add new token and code to save and load FPID nickname in board file.
* Add new token and code to save and load FPID nickname in s-expression net
  list file.
* Add WX_STRING_REPORT object to dump strings to a wxString object.

Pcbnew: better test for allowed layers when creating/editing Dimensions and some other Graphic items
Drc: fix comments and messages for some drc tests.
To do: fix issues in active layer selection when creating a track and layer pair selection dialog

* Use FPID instead of wxString in MODULE object.
* Use FPID instead of wxString when loading and saving files.
* Use FPID in COMPONENT object.
* Add wxString helper functions and comparison operators to FPID.
* Add fp_lib token to pcb and netlist file formats.
* Add code to load and save FPIDs to pcb file format.
* Fix segfault when deleting invalid footprint library tables in Pcbnew
  in non footprint library table build.
* Fix bug when counting the number of mod files in
  EDA_APP::SetFootprintLibTablePath();

* Remove defined CMAKE_INSTALL_PREFIX for Windows from main CMakeList.txt.
* Move footprint library path detection code from pcbnew.cpp to EDA_APP
  object.

* Add method to set footprint library table to PCB_BASE_FRAME object.
* Remove unused function EDA_APP::GetLibraryFile().
* Minor FP_LIB_TABLE object improvements.
