Add "watch" on test files change

[marty-wang]

Currently there is growl support, which is great. Would it be more useful when it works in combination with watching test files change? Thanks!

I'm not a fan of file watchers, it's something that people keep re-creating when you can just use watch(1), watch make test etc

but maybe :p we'll see

I've got watch working, but is there a way to retain the colors? A limited amount of googling suggests that there isn't... unless you know otherwise?

Ah... figured it out - you need to force colors on both mocha and watch:

watch -n 10 --color mocha -c
