A previous commit intended to remove the old PNGS and just leave the
new ones, but neglected to add the new ones resulting in the deletion
of all the PNGs. Um... oops.
The update to the new design accidentally left some old images. The new
design doesn't include resources for images we alias, and when the
directory was updated I forgot to remove the images corresponding to the
aliases.
Updates many existing emoji, and adds new emoji, including zwj
sequences for blended families. The updated emoji have not been
optimized or resized, run them through the makefile to get ones
similar to the previous existing ones. Not all updated emoji are new
renderings.
