Updates to the README file to instruct how to install everything necessa...

...ry to run the phpunit tests and get the js tests passing

I am starting at ground zero ... so I had needed to get my environment all set-up (which most people will take for granted). I added all of my steps to the README file.

I also add a package.json file to allow for jshint to be installed using NPM. I updated the .gitignore file to exclude the node_modules directory.

I add a .jshintrc file for the JS test to pass.

There is a problem in Cli/Command/RunCommand.php > outputPlain that is exposed by adding the .jshintrc file. The file is added to the $project->getFiles() array and then counted as part of an analyzed file. It's late tonight and I don't want to figure that bug out or even if it is an issue.

I am also using Vim on MAC which causes the "No newline at end of file" issue.
