Launch 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.

Settings: Comment out Google's bug report

This really feels out of place and does not serve a purpose in any custom ROM really.
On top of that, I doubt Google would seriously take into consideration a bug report off a custom
ROM.

I also think it confuses your average user when they try to submit a report via that option and
nothing happens....
