Implemented initial growl (lightweight notification) support.  Missing
from this checkin:

* animations (fade, slide down)
* hover mouse over dialog to pause/reset the alive timer
* progress style growls
* hyperlinks/html in growls
Added support for the user hovering over a notification to prevent it
from automatically going away.
Add fade-out animation to the growl dialog when it times out.
Added move animations to the growls when they fall down.
Growl/Notification windows are now pinned to the bottom of the browser
(by using bottom and right CSS properties + fixed positioning).
Refactored the growl service a bit in prep for progress-style growls.
Added support for progress-style growls.
Added support in the growl system for:
* progress style growls
* arbitrary widgets in growl dialogs

Also changed the dashboard upload to use the growl system rather than a
custom dialog.
Removed some testing code.
