CHANGED: Highlight net tool changed to highlight display toggle; moved to left toolbar
CHANGED: Multi-net highlight is now accessible when using the highlight net action
ADDED: Highlight Net and Clear Highlight actions to Net Tools context menu
ADDED: Default hotkey (Ctrl+`) for toggling net highlighting
The current and previous net highlight state are now stored and can be toggled
on or off with an action (no hotkey by default).
Highlight is now treated as a persistent state rather than a tool that is entered,
meaning there is no longer a special tool to enter in order to highlight nets.
Highlighting can be controlled while any other tool is active using the hotkeys
or context menu on a net object.
Tweak the icons for highlight net and layer display mode to better disambiguate them.

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.
