`jison` and `browserify` are global dependencies.

It looks like node-qunit-phantomjs and jshint are global devDependencies required too. This should be documented somewhere, as the npm run build instructions fail somewhat ambiguously if browserify isn't installed.

@gburtini thanks for finding this. I've added #15 to fix this. They are not global dependencies as npm run build is run with the packages installed with package.json
