Fixed the map annotation issue! Turns out I just wasn't setting the event ID, that's why it was null in calloutAccessoryControlTapped
Added a better description method for MZEventPlacemark, that really helped isolate the problem.
Fixed a string logging issue in MKMapView+MZExtensions.
Added a Default image for the iPhone 5.

TODO: We need an artist to make these screens look better.
