We want a macro that can "set the current move" for use in battle scripts, for setting how the animation should work. This needs to set a low-byte high-byte pair based on a move id, which requires 2 separate commands. In order for this macro to work, the code needs to be able to read the two split bytes as a single value, and write the single value as 2 split bytes. This is now supported.
script args should be able to handle <null>
don't add/remove runs inside the method that isn't supposed to touch the runs collection
handle race condition where UI may be aware of tab being removed before ViewModel gets a chance to notify it
fix bounds checking in map editor collision counting
better default value for newly added map script tables
fix width/height double-check when failing to import multi-sprites
fix cutoff text
fix spelling error
