First release

I have a first release of the app on the Play store now:

There is a rudimentary ability to crop images on it. After selecting an image to use for the card art, it sends it to the built in crop function of the Android camera to crop to the right size. There have been issues with this (as using the built in camera crop is not recommended as it is an undocumented feature), so there should be a fail safe where it will just use the image selected before cropping. My plan going forward is to find a cropping library and use that, but it will take a little bit longer to sort out.
