Update to 1.0

A few bits of polish have been added now that we are not in voting lockdown from the LD jam!

• crates now use better collision code, should help prevent the "not actually hit but counted" issues.
• kobold speed is slower, by just a little bit, to help make aiming less frame perfect.  This mainly comes out to about the same difficulty, because...
• houses now only collide on the bottom, no more roof collisions.  This makes them a little harder to hit but more accurate to what the space should be like.

Enjoy the update, and go break some packages!
