The user is now able to upload an avatar, and pick one in a list.
This functionality should eventually be abstracted in a community
package but we still need to work on a great public API. We rely on
collectionFS to manage uploaded avatars. We also removed
bengott:avatar which was trying to solve the wrong problem (namely
displaying the avatar, which is as simple as displaying an image), and
not a avatar system as it should be.
Gravatar support is coming (back) soon. We may also want to have a
list of default fun avatars the user can choose instead of uploading
its own one.
This component wasn't used anymore. We'll probably need something like
that again in the future, but we'll try to use a generic component
from Atmosphere.
