new changes in db branch causing issues

[kentywang]

• chat message sometimes show up three times
• being eaten sometimes crashes the game for client
• sometimes no one can rejoin a room
• player moves too fast and bounces off to orbit
• console shows cannot read property 'nickname' of undefined

I will try and find how to reproduce these issues, but they seem to be introduced with the db changes

I'm pretty sure most of these issues are due deployed db not being seeded/set up correctly. I'll try to deploy to dev again and debug.

I merged your changes into master, and pushed the build to dev heroku.

One issue I found was that I got "You left [object object]'s orbit" when leaving orbit.
