Blocking code

[laggycomputer]

I'd like to point out that requests is non-asynchronous code.

Though it's a very good library, it is simply unusable with discord.py. Any requests will block up the event loop/thread and can cause Discord to disconnect the bot in some cases.

I'd strongly recommend using aiohttp instead, and setting a ClientSession to an attribute of your bot object to handle web requests properly.

I'd be glad to PR this.
