Title: Add loading of artwork in other formats as well as .png

This is a patch I put out on Sourceforge some time ago, but it was forgotten somehow. It adds functionality to load images in all formats a QImageReader can handle.

Also includes pixmap caching from old-master, that part's not my doing.

SVGs for 0.4.x era B&B editor loaded and resized to ridiculously wide:
