Currently all our telegram.* classes are all jumbled up in a single folder, and it's starting to get a bit unwieldy. I propose we split it into a few folders - much like the telegram documentation also does (Inline, Games, Payments).
We can still have everything exported in the telegram module (and we really should), so it should be fully backwards compatible provided you've done something like from telegram import User or simply import telegram, - in fact the only time it wouldn't work is if they've hardcoded the module such as from telegram.user import User, but I've never actually seen anyone do that, so I think we're fine.
