Settings: We want consistent then we should do it like that

This commit is a first step to be consistent on all places. It sorts
and names all bindings (hardware key, navbar, navring) same to be
consistent.

Next step will be adding features from navbar to navring to hardware
keys and other way round.

Also some string corrections

HINT: Hardware key bindings values will stay for first because
of hard coded values in frameworks_base. For a full wipe release we
can change it then.

cheers
