Add the ability to change the profile name/photo in the new avatar bubble.

This will now:
- show a "Change" overlay button when the active profile
photo is hovered over (like we do in the CrOS 
chrome://settings page)
- when clicking on the profile name, show a textfield that
allows the profile name to be changed.
