Last fixes and a remove

we have already a damn stable base....although small features broke
or were removed during merge

- brigtness slider fixed (new API)
- toggle fullscreen on keyboard fixed
- autorotation keyboard fixed
- pie hide trigger keyboard fixed
- keyguard showed transportcontoll twice -> fixed
- removed the double tab code for home button....it does not make sense
with our current rebind implementation. Due that we plan to overwork
and centralize this as well like we did last time with a lot features
we will recode a more generic solution then google did

Only two things which are left is rambar das not show up and
QS layout needs to be nicer

All other is working as stable as usual
