Bug Fixes & Minor Updates:

COMPLETED: EventFragment, LodgingFragment, CostSummaryFragment

        EventFragment	- saving Event type selected to SharedPreferences
					- restoring Event type from DB when editing an Event
	CostSummaryFragment	- updating lodging costs
						- addition of cursor.moveToNext() to avoid an infinite loop

Other minor updates to Lodging & Event Fragments for mostly code cleanup / default strings
