Add test for reconnect.
Run each test for both parsers and both IP versions.
Don't save a reference to this nodified assertion function.
Add DEBUG env var which enables extra debug logging in node_redis.
Remove Grunt, run Redis on 6378 for non-interference.
Remove the tests already ported to Mocha.
Port reconnect after pubsub test; add subscribed after reconnect test.
Reconnet after pubsub test confused me. I don't think it tested
anything, and it didn't pass for me after I ported it. I've disabled it
and added a note. In its place, I've added a test to make sure we are
still subscribed and can receive pubsub messages after a reconnect.
Move test suite config-like stuff into a library.
Move test suite createClient args generation into the config library.
WIP. Some select tests, most disabled and still WIP.
