0.9.0-alpha Remove user events channel buffer

The main change in this release is #59, where an infinite loop for each user waiting on a Channel is removed and replaced with individual ad-hoc coroutines for each user-directed event.

This is release hopes to address a bug present starting in 0.7.0 (specifically #47) where the server dramatically slows down responding to requests after a few hours and general slowness.

The current mostly stable version of the server is 0.6.2.
