settings: allow to disable quicksettings

on 4.3 we had an extra settings option for it. Due that we want
to reduce the settings to improve the UX and due that
we are doing it this way on all dslv settings we change
the old 4.3 way.

Now it is very easy like dslv.....remove all tiles and QS
is completly disabled and cannot be opend any more. Notification
drawer shows the settings icon on the top right in this case.
As well compared to 4.3 this works on phones and tablets

Code cleanup and follow AOSP code style guidelines.

Some minor dialog tweeks (help dialog etc)

settings: add and pimp several help/reset dialogs
settings: google please cleanup your translations....Settings cleanup

it is really at the moment a nightmare to see compile errors when
getting 100000 of warnings. Whatever we removed already on some
packages the warnings....but still a lot are there
