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.
