Add animated display of startup notification

Browse Source 
The shell design says that upon launching an application,
no X window should have focus, and we should display an
animated launching indicator.

Implement this by in panel.js, keep track of the last started
application.  If there isn't currently an X focus, show an animation
for the last starting application.
