Add mocha tests in node

[jonotron]

I've been trying to get some AMD modules build for the browser to test with mocha in node to no avail. Would love to see how anyone has been able to get this to work.

Fingers crossed :)

+1, very curious to see if anyone has gotten mocha to test AMD modules in node.

I haven't tried this yet. If someone gets to it before I do please send pull request.
