Add AppOps

Settings: Add link to AppOps
Settings: Make app ops more usable
gets rid of the arbitrary categories,
shows all operations, not just the ones that were in use
operations != permissions. app ops is not permission management
PS2: Hide the tabstrip as we only have one category
Improve app op details layout.
Display Settings: Better font size control

Use a SeekBar instead of a list/spinner to determine the font scaling.
For consistency, an approximate size (small, normal, etc.)
 and the exact percentage are displayed.

Show a preview of the selected font size immediately

Modified the font size preference dialog to show the user the selected
font size immediately. Also split the size description and percentage on
their own lines to show a preview of two different font sizes. In
addition, removed the gigantic title bar from the dialog.
