Start with a blank TCP module and add a simple Netty-based server. Also moved the Registry.
Moved helper method for creating events from Fn.event to Event.wrap, which is a more logical place for it. Also created longer-named alternatives to $, R, T, and U on the Selector implementations themselves. This should help people who are freaked out by the $.
Merge branch 'selector-create-alternatives'
