use forked 'marked' repository
customize emoji rendering a bit
bugfix: submit content as plaintext always. render markdown-to-html on each render pass instead of burning it out on save.
bugfix: keyup seems to be more reliable for input mirroring than keydown.
convert standard emoji to text emoji (:emoji: syntax)
significantly better form styles (edge obfuscation, better submit btn)
housekeeping: force long content without breaks to break/wrap.
Merge branch 'emojis' into input-textarea-ui
housekeeping: move emoji configuration out of 'new' template, into pre-template config
housekeeping: use `.on` for submit event handler, not `.submit` alias
