updated scenario for cave.
Merge branch 'develop' of https://github.com/4950/ShittyPrototype into shak/Monsters
tried to do tile based collision. Got it sorta working for the player (currently disabled). Cave map collision is a bit wonky, and I don't know why.
Merge pull request #189 from 4950/shak/Monsters

I will merge it then. Blame Shak if it breaks the develop branch.
