Html5 new layout
HTML5: cleanup and fix errors when a new user joins the session

Most changes on the method WebsocketConnection#_onUserConnected()
The server doesn't crash as much as before when a user joins.
HTML5: restructuring the classes in the node.js server

Restructured the classes that read or write on redis to make more sense. Now
there's a single class that makes the bridge between redis and websockets,
and helper classes to publish to redis and to do any other actions on redis.
HTML5: update redis to 0.9.0, solves a few bugs

Apparently solved errors on user joins, the error was:
Error: node_redis command queue state error. If you can reproduce this, please report it
HTML5: fixing undo and clearPaper events in the server
HTML5: comment out wrong method call in RedisPublisher

Temporary, the method called doesn't exist anymore. Have to check it better,
but commented it for now so the app doesn't break.
