rework

@alexdavid had told me he stopped using this as mocha is enough now. I have a few projects that I transitioned back to mocha pretty nicely as well. Thoughts on making this a globally installed module that you run in a project to get yourself setup?

It installs mocha / sinon / chai, creates the test helper file, and creates test/mocha.opts with the same defaults mycha.yml currently has.

@alexdavid @kevgo thoughts?

Sounds good to me. I also don't really have a need for mycha anymore with Tertestrial. Changing it to generate the setup would be nice!
