gemoji submodule updated
bump emoji-data to latest

so we know about variants
exclude variant images from source
manually remove dead images from build

these are the ones that had an error in old version of iamcal/emoji-data

this means old links will break, but YOLO lets deal with it and try to
get things clean and proper
rake build:all task

oh man this worked perfectly go filetasks!

looks like it rebuilt the ones that had variants created because of the
stupidity in gemoji where they were turned into symlinks, which changed
the mtime, but not a huge deal.
fix warn on redefine constant
regenerate emojifont

really this just handles that a few more chars are double byte now with
updated data (and thus this hack won’t handle).  but we can possibly
avoid using this altogether in the future with the new variant hack.
update js-emoji to 1a86f2a
