added habitrpg-shared as a submodule
User services and the way it is called changed from async to sync.
So we always get latest local user in a sync way. And we keep updating model doing async server\API requests.
Basic fetch/User object references fix
Indentation fix.
Algos\items to be taken from habitrpg-shared.
Old .js files removed. Please someone fix references for CSS files and verify that CSS\images in habitrpg-shared actually updated. We should get rid of "shared" folder and user "./habitrpg-shared" subrepository instead.
