Don't bring home to the front if we're opening a floating activity

Give floating flag to previous activities in the stack
When launching stacked activities, only the last one is flagged as floating in sysui when tapping halo.
This causes the system to show the launcher when the first stacked activity is launched (this first intent gets the flag FLAG_ACTIVITY_TASK_ON_HOME
in TaskStackBuilder).
This change makes all the stacked activities get the floating flag if the last one has it.

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.
