Put FP_LIB_TABLE::Footprint*() functions on stage, but comment out lazy plugin lookup trick in FindRow() until these new API functions are used.

CTL+X, CTL+V, CTL+A, CTL+C

Remove tooltips from fp_lib_table wxGrid, were annoying and munging wxGrid's grid.
Change initial size of DIALOG_FP_LIB_TABLE.

3D viewer: Preference menu: fix a bug which displays incorrectly the actual display options state (always shown off) when starting the 3D viewer

3D board display: better rendering of the board: the board polygon outlines (generated by the specctra function which calclaltes outlines) is now used to create the 3D body of the board,
in pcbnew and cvpcb.

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.

Removed some Microsoft Visual C centric definitions in CMakeModules/config.h.cmake which were tripping up the mingw-w64 build

Paste popup menu in this dialog now allows pasting a (fp_lib_table)
s-expression element holding (lib) elements.  This provides an 
opportunity for GITHUB library publishers to put the table description
into their README.md file as a (fp_lib_table) element where it can
be quickly copied to clipboard and pasted into the fp lib table dialog.
This is a paste operation, and overwrites from the initial cursor position.

Fix throwing of IO_ERROR in plugin.cpp by converting function name to wxString.GetData().
Switch to const PROPERTIES* in GITHUB PLUGIN functions.

Enhancement in Excellon file reader: accept Feed Rate and Spindle Speed definitions in Tool information line (but does not use them)
Eeschema: better name for m_SheetList (changed to m_SheetPath) member of class NETLIST_OBJECT.

Eeschema: better name for m_SheetList (changed to m_SheetPath) member of  class NETLIST_OBJECT.

Eeschema: netlist generation: fix bad choice for the "best net name" when selecting a net name between labels connected to the same net.
Code cleanup and remove unused file.

* Use wxAuiManager perspective to save and load window settings which should
  allow us to start using more advanced wxAui features like detachable tool
  bars and windows.
* Remove sash size change events, event handler, and sash width clamping code
  since it didn't work all that well anyway.
* Disable the close button on the footprint view pane.
* Update the footprint list box selection when iterating the list using the
  tool bar arrow buttons.
* Merge code from modview.cpp into modview_frame.cpp and remove modview.cpp.

Make pretty prettier by striving for single line module pads.  Add slick std::string based strprintf(), twice.

Mainly, fix an annoying issue about not named nets:
now, these nets are named from the component references and pin names which are connected.
therefore, unless the net or the footprint references are modified, the net name is not modified between 2 netlist calculations.

Netlist generation code still needs some code enhancement (mainly removing the global g_NetObjectslist variable).

Add const PROPERTIES* to FootprintDelete().
Add {Get,Set}Properties() to FP_LIB_TABLE::ROW.
Touch up fp table dialog.

Fix an annoying issue about not named nets:
now, these nets are named from the component references and pin names which are connected.
therefore, unless the net or the footprint references are modified, the net name is not modified between 2 netlist calculations.

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.
