🔥 custom emoji

On GitHub.com, people predominantly use `:octocat:` and `:shipit:`, but
other custom emoji not as much. These two most used custom emoji also
happen to be specific to the GitHub brand, so it makes more sense that
we add them as custom emoji in the app itself rather than shipping them
with the gemoji library.
