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.
Also allows some symbol lib operations when we know the context even
if the library itself isn't selected. (For instance, select a symbol,
copy, paste.)
Some differences are due to difference between libraries being files
in symbol editor and directories in footprint editor, but this unifies
most of the rest.
It also dispenses with the save-to-library vs save-to-document distinction
in the GUI because it makes for too much variability in the GUI, was
implemented differently between the two editors, and isn't needed as much
anymore now that we have the highly visible infobar.
There was also an issue that the save-to-board icon occupies the same
location and has the same size/shape/colours as the Board Setup icon in
PCBNew.

Prior to this change the "Save As.." command would take a different action
based on the state of the editor which could be confusing. There are now
separate commands for saving the currently selected library or symbol.
CHANGED: The implicit save as menu entry which would save the currently
selected library if no symbol was selected or the current symbol to a
different library. There are now separate save as commands for libraries
and symbols to make it obvious what is being saved.
