profiles: add basic profile mapping

 * Each profile is mapped to its preference file.
   Meaning, if deleting one, the pref file also gets deleted.

 * If a profile gets deleted, the pref shouldn't just be cleared,
   it should completely been removed, thus we need the shell command
   and a small check, if its really gone.

 * Cleaning up a few things here and also set object as finals
   where possible to get some small performance.

helpers: add a simple root check

If the device is not rooted, there is no point in using
this app. Show a small dialog which informs the user
about this and exit the app afterwards.
