Updates initialization of Image(frame:) and fixes bug in Generate #675

@aleph7 I finally remembered why I had set the contents in the first place...

When creating an image from a filter like this the coordinates of the CIImage are {0, -h, w, h}, so setting a UIImage like this:

self.imageView.image = UIImage(CIImage: output)

Results in the image not showing up... i.e. since the original image data is placed -h the contents of the new UIImage are empty.

This still looks weird to me. Let's follow this SO answer: http://stackoverflow.com/questions/9094058/creating-uiimage-from-ciimage#9615090
