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.

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.

On-the-spot preferences

Allow for handling of resetting multiple preferences individually.

Present the user with a list of active on-the-spot preferences to
choose from.
If a preference dialog was never presented to the user, it will not
be available for reset.
If only one preference is currently active, a simple reset dialog is
presented (current existing dialog / no list)

PS1: Initial commit
PS2: Use defined strings instead of decoding the SETTINGS_TO_RESET variables.
     This allows for string translation.
     String names should be equivalent to the SETTINGS_TO_RESET variable.
PS3: Add some error checks
