[Desktop13.04-Topic] Stop relying on GNOME fallback code for unity

[Sebastien Bacher]

Hey everybody,

One topic for UDS, since GNOME is talking about dropping their code for 
fallback to just use gnome-shell, we should make sure we stop relying on 
that (it would also be good to stop relying on not so maintained code)

Things I can see in that category:
- turn the "bluetooth indicator" (patch over fallback-session code from 
upstream) to a proper indicator
- turn the "keyboard indicator" (the code we patch is going away in 
GNOME 3.6) to a proper indicator
- deal with disk mounting in unity (we use the GNOME fallback-session code)

(It would be good to have design input on the indicator before we start 
if we are going to do that, if we rewrite them we can as well do it in a 
way which improves the design)

There are probably others things in that category but those are the main 
ones I can think about
