Merge pull request #17 from tmoc/tom

Got rooms and lobby functioning as originally desired.
Adding in initial server side implementation with very initial user
model.
more work on user layer
fix module list at top of app.js
initial save to database now working
User sign-up is now working.

Still needs some testing and debugging, but handles basic simple use cases.
Merge branch 'davidderiso'
Added styles to lobby.
