Add example test with grunt and mocha.

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.
