Remove Gravatar from core and add new hook avatar_lookup.

This patch removes all occurances of Gravatar from friendica's core and adds a new hook "avatar_lookup" inside the function avatar_img($email) where the new *avatar-plugins should hook in.
I haven't touched the language files yet. Are they updated automatically somehow?
