Refactor to remove `phantomjs/main.js`

[pconerly]

Hi,

I don't have a specific solution but I think that the current organization of grunt-mocha leaves something to be desired.

Should there be a separate copy of phantomjs/main.js within grunt-mocha? I know you made a modification to it, but I feel like it would be better to see if we could just pass in the required grunt-mocha options into the existing grunt-lib-phantomjs/phantomjs/main.js file.

Thoughts?

I agree!
