v7.2 Key-modifier fixes
This release mainly focusses on fixing small bugs, most of which were in the key-modifier tracking.
- Fix modifier keys not being highlighted when key-modifier tracking is on.
- Fix modifier keys releasing every other key when key-modifier tracking is on.
- Fix the key-modifier check box not being toggled when loading a config.
- Fix all known cases of key-modifier tracking weirdness.
- Rework key-modifier tracking internally to be more efficient.
- Lots of internal optimizations.
- Better color support for unfilled grids (empty tiles are now either the background color or transparent depending on whether transparency is enabled).
- Fix several minor bugs in the right click menu.
