Update version to 0.1.1-dev for continued development, and update dependencies
Update for latest nightly. This also renames create_and_connect() to run(), and updates run() to run the dispatch loop in the current thread rather than creating a new one, as rust will no longer allow any other threads to live after the main thread exists.
Add support for using the channel option on IrcMessageEvent.
Add nick change tracking and channel tracking to tracker.rs
