Settings: Use hardware acceleration for selected applications (2/4)

Move HW Rendering app to System/Performance section

Allows controlling of HW rendering individually for any application.
This is usefull for applications having the "blank white screen"
bug (gmail, facebook, ...). Turning off HW rendering for these application
eliminates the white screen bug. As a side effect, the application UI
will become more laggy - feels like in gingerbread.
