Test file watchers that triggers edited tests

[villasv]

I wish testify was able to watch the test files and after editing one of these, it ran automatically after a short time.

This is kind of what WallabyJs achieves and it's pretty awesome :-)

Wow. That's a very ambitious feature addition! It makes me very excited.

I'll check WallabyJs out and try to think of how to implement this. I guess I'll need community help on this, but I think it's a very good idea.
