also town map code relabelling
YamaArashi just did town map relabelling but oh well
I aleady made the changes and don't feel like redoing it

rename functions, clean up address/wram comments, other misc
only broken up so that all changes are viewable on github

Using 'Coord =' doesn't like using wTileMap
So use hlCoord, deCoord, bcCoord, aCoord, Coorda, or dwCoord
to avoid static addresses

For unknown addresses, use "w<address>".

Label overleads are still an issue.
