This script copies iPhone images (Resources/iphone/images) and splits non-retina and retina graphics into MDPI and XHDPI-densities on Android (Resources/android/images). So I only have to work with the iPhone folders when settings up image resources, this script handles everything else.

To do: Scale images to LDPI and HDPI (if this is even needed?)

Scales for HDPI now at least. We'll see if I need to add LDPI or not.
