Settings: Silently update the package manager

This commit implements automatic updating of the "Choose application"
list used for creating configurations for new apps. The list is now
being updated each time an app is either added to or removed from the
existing custom configurations.

Settings: Skip apps where the LED's already set up

The Settings app should not have shown a package in the "Choose
application" dialog if it was already configured with custom
notification lights since it just introduces confusion

Add fastscroll to the Manage applications screen

so you don't need to scroll so much if you have alot of apps
and want to go to the bottom of the list.
