Fixes #299 - Added width/height labels to custom image size fields; compressed screen components so buttons will be visible on 3.5” iPhone.
Tap on custom image size screen to dismiss keyboard (and show potentially hidden controls).
Integrated tap-on-view-to-dismiss-keyboard in existing tappedOnView handler.
