Contains following improvements:

• Use latest version of ImageMagick

Imagemagick is now embedded in the bundle and doesn't need to be installed globally anymore. 🎉

This is basically a MVP release. I've used it to correct hundreds of images, so it works and is already quite useful, but there are a few limitations:

• Imagemagick is not bundled and must therefore be installed globally
• Due to a render bug of gloss the initial view is a little broken and one needs to rescale the window to force a redraw
