FW: Statusbar Brightness Corrections

AOKP (ROMControl) statusbar brightness control code fragments still remained in PanelView.java, this was conflicting with the change to CM based brightness control. Removed the final sections remaining from AOKP.

Removed one import from BrightnessTile.java that was not needed.

This should finally resolve the issues regarding Statusbar Brightness control.
