add option to optimize PNG images with optipng
This can decrease package size by optimizing PNG image size. Images are just stored with better compression and/or filter options. The actual image content is not altered. Additionally this can automatically fix broken PNG images which caused some trouble lately. Signed-off-by: Christian Hesse <mail@eworm.de> Signed-off-by: Allan McRae <allan@archlinux.org>
