Settings: Remove "Make pattern visible" regardless.

  - Previous logic depended on all pattern lock elements to be
    null prior to removing the preferences. Remove them one by
    one if they exist now.

  - PS #3: Add braces.

Settings: Handle navbar heights correct on dpi changes + more (2/2)
Till now we set the height in px in the settings. Which is a problem
especially on multiDPI roms like we are when the user afterwards changes
the dpi due that it isn't calculated correct anymore on the new dpi.

This commit does
- save the dp value in provider and calculate the real px in fb
- clean up the settings stuff for it + do it a bit nicer (only settings part
  where we do not set the value for the listview)
- add Converter class for common methods we always use....till now only px->dp
  and dp->px method

Toggle nav bar through power menu (2/2)

- This is highly based on this commit form SlimRoms: https://github.com/SlimRoms/packages_apps_Settings/commit/30482e059fb55b9d3aa4d461a0715d77ec70776a
- Now we can toggle nav bar on/of in power menu. It's easier to use PIE.

Thanks again to @kufikugel
