Unvalidated ORIGIN address persisting and restoring correctly.
Destination entry working correctly.  UI details still rough. 
Known: destinations currently not being persisted.
Removed "Add Destination" button.  Not needed anymore -- woohoo!
Fixed origin validation/persistence/behavior.  Known issue where origin
and destination validations are not using a lat/lng centerpoint.
Fixed the kluge way address strings were being stored in the Address
objects.
It works!  Origin/destination entry and validation working.  "Route It"
is working.

Known issues: addresses not being persisted yet, destination address
validation is not using origin lat/lng as centerpoint yet
