Add EOS Daydream into SystemUI

PatchSet 3: Fix manifest derp

Initialize and store values in SettingsProvider because
the Settings and the Dream are separate activities.

Implement interface to notify DreamActivity
when values have changed. No need for ContentObserver
as values are set when dream restarts.

OnPreferenceChange returns false if user inputs a
number greater than MAX_MOBS

PatchSet 4: Set and update mob count summary

Initialize interative boolean when service starts
NPE check on on settingsListener

PatchSet 5: remove settings changed interface
use a static boolean to determine if dream should
reset
