I marked this ready for review even though i still don't know if we should provide the ability to cache app emojis at startup, as you can see i did put a boolean argument but didn't implement any logic for it so far.

I'm strongly in favor of splitting the models into a GuildEmoji and AppEmoji. The current approach is pretty much saying "an Emoji can have both .guild_id and .application_id, one of, or neither!"

Anyhow, minor nitpicks below.

If we want to split them into different classes (I had this talk with @shiftinv in the past, but at the time they said it was fine to go with this approach) we would most likely split them into Emoji and AppEmoji to minimize breaking changes

@shiftinv did your opinion change on this?
