Removed Waterline ORM, using mongoose now. Need to fix profile widget saving (currently not working).
Resolving merge conflicts.
Fixing issues as a result of merge.

Suppress terminal output for disk usage. Fix bug in UserService (wasn't using userId for user lookup. Fix bug in profile-widgets-controller (profileObserver was observing 'profileId' instead of 'profile.id'). profile-widgets-route renders into a named outlet (fixes broken add widget popup).
