Code tweaks, Travis and documentation updates.

@kmiyashiro:  Not ready to commit yet, I want to make docs look closer to the grunt-contrib module quality. 

I made a ticket at gruntjs/grunt-contrib-qunit#17 and asked how they have `/docs` generate into `README.md`.

I also inquired about what the standard for a module like this to be apart of `gruntjs` repository and keep maintainers. Would that be something you would be open to if they allowed it?
