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.
