Migrate to jasmine 2.0

Closes #1 

There's a little problem that we need to solve: the socket.io and sinon both use a index.js. Socket.io rewrites the sinon's lib, so I had to change the bower.json and filename of sinon, so this wouldn't happen.

There are still some "pending issues":
 * take care of deferred tests
 * a xit test

Otherwise migrated and good to go
