Automatically convert invalid jpg pics

Well, seems that's Qt's ImageReader got pickier regarding jpeg-files. If
the resulting QPixmap is null and void, try to convert them to png.

This introduces a new dependency to ImageMagic++. I don't like it, but
it works, kinda... I saw random crashes while testing...
