Request for overview images, one "global" and one per set.

What a collection! Thank you.

1. It would be valuable with a big overview image that simply shows all icons. It could be any file format. It would make sense to have it at bottom of front git page if possible.

1b) ...same per specific set. I.e all icons for, say, "Bootstrap" in one image, and put under that branch.

@twMat Images might be huge! I will figure out a proper way to do this before 1.0.0, and if you have any suggestions, please let me know.
