Secondary Emoji Codes

Like normal emojis have different texts to type between colons to access them, custom server emojis could also have secondary names to appeal them, but those would get overridden if another emoji has an identical PRIMARY name. To decide which overrides which when dealing with identical names of the same level, we can base ourselves on how high the servers are in the user's list, or add a manual way to specify our favorite servers in some advanced settings.
