Settings: Quiet Hours Extra Daily Times (2/2)

Users complained that, for example,
	setting up weekend hours
	but then moving to weekday
	hours within the same day
	was previously impossible.

This allows...again...much further
	customization than even the
	updated and super custom times.
	After this there is no reason
	to complain =P

These are still only called as needed (boot,
	state change incoming, time changed)
	which is still much less polling
	than each haptic touch polling
	3 settings, creating a calendar
	object and comparing times...
	Each call, notification, etc...
	So I have no issue with it.

Also add a "reset times" button for
	user convenience.

PS2: Add preference categories to make it
	easier on the eyes
     Logic fixes and make unused preferences
	more obviously unused via setting
	the time summaries to "- - : - -"
     Set QuietHours summary to enabled pref
