Done. The changes to common_strings.c are mostly to prepare for EU/JP languages. Same with personality_test1.

The other stuff is quicksave dungeon serialization.
There is the regular saving which uses bit reads/writes rather than these byte read/writes. For example:

WriteDungeonLocation refers to quicksave where it serializes per-byte.
WriteDungeonLocationBits refers to regular save where it serializes bits.

I didn't rename all the Bits variants because it's a lot and I didn't want to touch that code yet. The quicksave stuff is the stuff I dealt with
