Never-ending recess task story: minor code change
Changed jshint task to src-dest pairing, changed Gruntfile accordingly. Fixed ident rule in .jshintrc
Add es5-shim to bower dependencies (which should be a good idea for IE8 and below)
QUnit testing framework:

 * added a dummy jQuery plugin and its unit test (intentionally failing one assertion)
 * added runner.html to let a browser run the test suite
 * changed index.html accordingly
