Updated the maps from dropbox
YES. We now collide with any obstacle layer
Modified collisions:

Now we check for collisions against any layer that has the "obstacle"
property, and resolve callbacks on layers that have other properties,
like "destructible"
Merge branch 'master' into collision
Woo! Fixed that nasty collision bug
Merge branch 'master' of github.com-variousauthors:variousauthors/LD29
