Battle Tent Port

This is...most of the stuff necessary for the Battle Tent to work. I've faithfully restored most things so far, including doing a few grammar tweaks.

Main issue is that we get a really strange softlock when the Pokemon selection menu comes up. Not sure why, but point is, it can't progress to the next bit for debugging like this. Committing now to ask for assistance.
