Share indicator about cozy-files

I agree that would be nice.

May be we can separate the "share" icon (actually named "send" right now) and have it change depending on file status :
http://fontawesome.io/icon/lock/ for private
http://fontawesome.io/icon/globe/ for public
http://fontawesome.io/icon/users/ for limited (and put the number of people before, like
"2 :person_with_blond_hair:" )

We could also add the possibility to share by tag but i think it would be another feature.

Our fontawesome version is old, we don't have the "users" icon just the "user" one. So I'm going to update it crossing his fingers that it won't break everything

didn't cross hard enough :p
