Small change:

non-admins:
- if there are unvalidated contributions waiting for a movie, it is shown bellow the list of contributions (top right corner), it can be useful to know if something is already waiting for a movie.

admins:
- now it is shown from who are the contributions which are waiting (so you directly see if it is from someone who usually is reliable or not )
- when validating contributions without pictures, the name is not added to contributors list
