Improve Tinted Status Bar Tint Detection

1) As stated here,
https://github.com/MohammadAG/Xposed-Tinted-Status-Bar/issues/23 , the
main intent is for internal use and changes unexpectedly to 3rd party
use, so we use the GravityBox intent which is also called.

2) Also fade the charger view as it might be visible as we change.
