wx/wx.h includes all wxWidgets .h files, and sometimes creates collision
names in #define between kicad and windows headers
Moreover, blindly including a lot of useless files is compil time consuming
Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
This leaves the decision to check/enable menu items to the main UI
conditions, and only the menu has control over showing/hiding the menu
items. Also rip out a special case for the preferenes item that isn't
needed on OSX anymore since all the main menus have been moved to
ACTION_MENUs now.
This allows for the tool framework to keep track of a universal
set of conditions for the UI state (enabled/checked/shown) for
controls of actions. It removes the need for the main menubar
menus to be CONDITIONAL_MENUs and be rebuilt on each open,
and instead makes the updates of the check and enabling of
items handled in the native wxWidgets way.
This commit switchs the 3d viewer and kicad project manager window
over to this system.
* Push a function into CONDITIONAL_MENU that adds the item
* Modify the tooltip for close and exit items to have the
program name

SELECTION now holds EDA_ITEMs not BOARD_ITEMs so various places had to
change to casting the selected items to BOARD_ITEMs.
Fixed compilation warnings on clang (Tom)
