Fixes

Add SeekBarPreferenceCHOS

Fix navbar tinted
Settings: some build fixes
Adjust animation scale range.

The animation scale options are _developer_ options for a reason: They
allow _developers_ to assess and debug animations in the apps the're
developing. A max scale of 2 is not sufficient for that purpose, so
increase the scale.
