WIP: fix(tests): A first attempt at a sane pattern to begin testing the handling of the protocol.

[jirwin]

This is by no means a finished product. Just a jumping off point to get a discussion started.

What

package.json: Change the test script so that we only test files in the test directory that start with test-
test/mockircd.js: A simple mock server that allows us to send and receive data, and makes that data retrievable later. This isn't supposed to be an implementation if an ircd, more a tool for unit testing.
test/test-irc.js: The beginnings of testing the irc part.
test/test-parse-message.js: Renamed so that it would be run by npm test. Removed an unneeded jshint line.

Todo

• Figure out some fixture system for long 'transactions'
• Prioritize parts to be tested first so we get tests out sooner than later
