Removed upside-down orientation as we don't use that at all in this app.
Added Google Analytics for iOS 2.0 beta 4 and started measuring UIViewControllers. MapViewController, ListViewController, and SpaceClusterViewController don't use the GAITrackedViewController because MapView was the only one that would track.
Implemented Google Analytics tracking for Filters.
SpaceClusterView was getting tracked twice - once as "List View" and once as "SpaceClusterListView"
When the List View reports to GA, also send which kind of list view it is.
