Ombi: Integrate with profiles, Retire user defaults

NOTE: If you previously used the Ombi integration, New ombi users
won't be created until you set this up.

Ombi settings can be added to a profile in Settings > User Profiles.
The "Modify settings" options will now apply to ombi if the selected
profile has ombi settings.
