No keyboard navigation for libindicate based applets

[Luca Ferretti]

Hi everyone, 

I'm going to have a talk about Ubuntu and a11y[1] and I was checking
some stuff in a default Ubuntu setup.

My tests showed some issues, included this 
https://bugs.launchpad.net/ubuntu/+source/libindicator/+bug/519195

Basically, panel applets using libindicate are un-focusable. This is not
good for impaired users that can't use mouse or pointing device, but
only keyboard.

Any change to increase the severity and hopefull fix for Lucid?

PS more reports will come :)
