Weekly drop #12: increments and "events"

Lots of incremental improvements this week - better placement of map items (so important places aren't obstructed), getting the first quest fully playable, fixing bugs.

I am currently working on the "end of turn events" - things that can happen before the next dice roll. It's already in this build, but still has some bugs and needs to be extended. This is going to be the last major bit of game mechanic, hooray!
