adds node_modules/ to gitignore
changes to gruntjs powered build

The existing SpecRunner.html is still in /spec, I didn't see the need to change it, so it will still load the specs correctly. It will need to be updated whenever a new spec file is added, but I don't think this is too much work. The grunt build will automatically pick up new spec files and executes via the command line. Also, this will enable integration via Travis-CI so in the future we can have PRs automatically tested before we accept them.
