Title: Feature: download selection as PNG

I needed this feature to split a sprite into multiple images. This commit adds a new button "Save selection" which allows to download the current sprite selection.

It relies on [canvas2image](http://www.nihilogic.dk/labs/canvas2image/) and a new class `spritecow.RectSaver`.
