Fix crash when story contains a single picture.
Remove 'synthesize' directives and fix fallout. Replace '#define' with 'static NSString * const' declarations.
Merge remote-tracking branch 'upstream/UXDemo1' into UXDemo1
Restore 'synthesize' directives since this class needs to access the ivar.
If user does not select any images, return to the KSRootViewController rather than going to the KSStoryDetailViewController. Fix crash in KSFinalPhotoSetCell.  Renamed some constants.
