Migrate to asyncio

Python 3.5 added asyncio, an asynchronous IO framework similar to Twisted...

https://www.python.org/dev/peps/pep-0492/

This added new python keywords (async and await) which give callers more control over how they await asynchronous operations (for instance, asyncio.wait_for() to apply a timeout).

This branch migrates our stem.control, stem.client, and stem.descriptor.remote modules from a synchronous to asynchronous implementation. Usually this would preclude us from being used by non-asyncio users, but this also adds a Synchronous mixin that allows us to be used from either context.

In other words, internally Stem is now an asynchronous library that is usable by asyncio users, while retaining its ability to be used by synchronous users in the exact same way we always have.

Win-win for everyone. Many thanks to Illia for all his hard work on this branch!
