Initial commit
Deleted init methods I don't need, removed stuff not needed with latest compiler.
Removed synthesize statements, removed inits I don't need, over-rode initWithImage.
Replaced unsafe_unretained with weak (right answer, I think).
Animation options is now NSUInteger, so NSInteger should(?) work.
Replaced imageWithContents of file with imageNamed, good enough for this case.
Modified to use new type of SEDraggable based on UIImageView.
Added iPhone 5 image to satisfy build, updated to Xcode 4.6, IOS 6.
