Settings: Introduce Privacy Guard Manager

Due that on the one hand a lot user are not familiar
with permissions and how to read them and on the
other user want to have a faster easy access to
setup privacy guard for several apps this small
manager assist the user to setup.

Privacy Guard Manager shows a list off all installed apps
Per default it shows only user apps which have critical
permissions privacy guard can protect.
The user can optional show in the list as well all system apps
or turn off the filter to show all apps undependent of the
permission the app has. To activate privacy guard for an
app a simple click on the entry activates it so that the user
can go fast trough the list. Longpress opens app detail page.
Initial help dialog tells the user how to use it.

Due the filter user who are unfimiliar with permissions can
fast see which apps are effected without deeper knowledge

cheers
