find(User user) -> find(String email) when only email is required.
Added the possibility to find a user's contacts. Also not adding owner to own circles (no use).
Streamlined spaces and circles views. Better text when no records/users where found after a search.
Small change since owner is no longer a member of his/her own circle.
Showing all users except owner when adding new users to circle.
Minor change in CSS concerning margin of tab content.
Now giving the possibility to add users from your contacts to a circle, or search in all users.
