Almost got everythign working.

Issues left to resolve:

 * Removing a reaction doesn't properly remove it from UI, but the event
   is recorded correctly.
 * Since contacts are not being saved there will be issues with
   "following" users and you could overwrite your follower's list with
an empty list.
 * Caching is no longer working.
 * I skipped chat room implementation.
 * Rendering shared event's doesn't work and needs to be revised.
