added in refreshing the bots after every swap from arena mode to edit mode.  Every time we move from edit
mode, the arena is cleared out and all bots are added back in.

This is mostly for wheels and other box2D attachments, so that they can get added into the box2D model after
they have been placed on the bot.

Wheels are closer, but it looks like some kind of backwards force is getting applied to them.  I'm willing
to bet that it has something to do with how I'm handling the transform, which is not the center.
