* rename WS_DRAW_ITEM_POLYGON to WS_DRAW_ITEM_POLYPOLYGONS (better name)
* use SHAPE_POLY_SET instead of std::vector(<wxPoint> to manage the set of polygons.
It also remove duplicate code related to HitTest and bounding box.
* fix HitTest and WS_DRAW_ITEM_POLYGON highlight.
eeschema now supports arbitrary colors for all object types, and
pcbnew does in GAL canvas. When switching from GAL to legacy canvas,
pcbnew will convert colors to the nearest legacy color.
Make all EDA_TEXT data private and rename accessors to avoid function
name collisions in derived classes.
Overload EDA_TEXT's SetTextAngle() and SetEffects() in TEXTE_PCB.
Add support for preserving Reference text position, size, orientation
during a netlist import into a BOARD, as well as the one off footprint
update dialog.
When the filename is not absolute, the page layout file is now searched first in project folder, and then in kicad template folder, if not found in project.
Fix issue when using a page layout file in project folder: eeschema and Pcbnew did not use it, unless using an absolute path.
Now, if the file path is nor absolute, it is seen as relative to the project (which is the expected behavior)
fp lib wizard: when pcbnew id compiled with USE_GITHUB_PLUGIN=OFF, the github plugin option is no more accessible (and the web viewer no more used).
Remove KICAD_GOST option because it is now useless: the 2 GOST options are now selectable at run time and are:
* specific page layouts (now user definable, and the GOST page layouts are available in template folder)
* notation for multiple parts per package (made in eeschema, preference menu)
Eeschema, dialog netlist: fix a bug when removing a plugin panel, when is is not the last.
dialog netlist:Add a predefined command string for python scripts, when creating a new netlist plugin entry.
* Add footprint library table loading to footprint editor.
* Overload FOOTPRINT_INFO::ReadFootprintFiles() to read footprints from the
footprint library tables.
* Fix a bug in FP_LIB_TABLE::IsEmpty() when the table has a fallback table.
* Add code to FOOTPRINT_EDIT_FRAME to use footprint library tables.
* Add an optional build time version of PCB_EDIT_FRAME::loadFootprints() to
populate netlist footprints from footprint library table.
* Remove adding footprints to board whenever GetModuleLibrary() is called and
move loading locally as required.
* Add missing source file license comments and coding policy fixes.
