Change-Id: If9cbc0b196371b138b238c847f96d4da749d154f
Settings: Battery Options

Until we find a suitable solution for displaying the text percentage
on the battery bar, hide the option.

Fix: Ensure lockscreen see through setting persists after reboot

If see through was enabled and the device was rebooted,
the user had to toggle the setting off and on again to activate.

Settings: SuperSU from Settings

If SuperSU is installed, show an entry in Settings below
"Developer options", which launches SuperSU when tapped.
At boot time SuperSU will detect if com.android.settings
contains the resources from this patch, and if so it
will hide itself from the launcher. This was implemented
in v1.85, so we only show the entry if the installed
SuperSU version is at least that.
