Added player-to-player interactions 

Players are now solid to each other and can push each other
Players can now attack each other (but they do not deal damage)
Players can bounce on top of each other, and they get squished
temporarily
Players are given slightly offset positions when they transition between
areas and levels, so they're no longer on top of one another.
