Settings: dslv do not allow to add recent, home, back main action twice

to have it twice causes problems on navbar pie and wherever in future
home, back, recents is used when the system disables this buttons and
more then one per feature exists. Due that a user do not set eg
2 home buttons on navbar let us block it and give the user a hint
that this is not allowed. All other actions can be added twice

Settings: remove always transparency mode navbar/statusbar 1/2

problem is that the transparency on most app totally break due
that a lot apps do not draw behind navbar and statusbar. Nearly
all user never use always mode and just use it on launcher
and lockcreen. So let us remove it

as well a bit cleanup in arrays and strings
