HTML5: cleanup on RedisBridge

Moved some methods that actually do things on redis to RedisAction.
HTML5: removing lots of unused or unnecessary code from the server

Cleanup the node.js server removing things that were not used or were related
to making the HTML5 client a presenter, which will not be necessary at this
first iteration.
The node.js server should also not change anything that's in redis, just read
it. Removed some of the code that changes redis.

Also updating the comments to match codo's format.
