Updating user picture

Problem/Motivation

Update user picture on profile or on user account

Steps to reproduce

When a user login on to our web site, user picture is not present because this module tries to write on user profile instead user account if we used profile2 module.

Proposed resolution

We solved this problem creating an image field on user profile and a hook where we copy the picture on user account if user account is empty.

But I think the best option it would be have a flag on user mapping that says on which field are going to sync the picture, on user account or user profile?

Remaining tasks

User interface changes

API changes

Data model changes
