We currently name the mixed-gender 'kiss' and 'couple with heart'
images after the single-codepoint sequences. But aliasing maps
the single codepoint sequence to the gendered sequence, not the
reverse. As a result the build doesn't create ligatures for the
gendered sequences, since it thinks the image doesn't exist.
Fix this to use the gendered-sequence-names for these images, and
let aliasing work as intended. This follows the convention we've
adopted of letting the name more completely describe the image
contents, and defining how to represent less-specific sequences
using aliasing rather than baking these decisions into each image
name.
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.
The new emoji assets (in sync with Android Lollipop) were slightly
smaller in size. Replacing with a corrected size.
Also update the font version to sync with Android again.
