Default Desktop Experience for 11.04

[Martin Pool]

One consideration about the applet whitelist: at the moment the Unity
Launcher invites you to install applcations like radiotray, whose only
UI is an applet icon.  (I think this is not the only example.)  This
is leading the user up a blind alley.

In this case there is upstream work to support appindicators, which is
great, but it requires manual xml editing and it's not in Natty
yet.[1]

It seems like these each need to be either
 * fixed before release
 * whitelisted
 * not recommended if you're running Unity

radiotray is not all that important of an application, but just having
nothing happen is icky.
