Re-implement Halo checks with MultiWindow

    1. Add halo state check, multiwindow will not cast on if halo exist.
    2. Recent panel popup menu: hide multiwindow option if halo exist
    3. If HALO is activated all HALO notifications will open in floating window
       If HALO is not activated notifications will open in mutiwimdow mode.
    4. Some cleanup
SystemUI: Custom Tile - add Global && Create Small API

Add forgotten Global table to Custom tile
Adjust Advanced Tile to directly change
	settings rather than sending an
	intent to the Chamber to loop and parse...
	and return to loop and parse again...
	Cleaner and more efficient

API:
Intent Broadcasted:
"com.android.systemui.CHAMBER_FIRED"
Extras:
"setting_key" > Setting being resolved
"setting_value" > Value resolved setting is currently
	set to.
"%" must be added as a flag per the usual usage of getting
	Extras to allow correct parsing.
	I.E. "%setting_key" and "%setting_value"

Intent can be caught by many profile management apps
	such as tasker and llama.  This allows the
	user to catch this intent and change profiles
	update settings, etc. Given that only advanced
	users are using this process anyway, it will
	only be called by those who might take interest
	in using it.

rebase
