Add basic JS file
Remove "use strict" from global scope

It just seems like a bad idea to me.
Make jshint happy
Merge branch 'refs/heads/master' into PW/base-js
Improve robustness of no-js/js class switch

HTML element always picks up the js class, regardless of no-js's presence.
Namespace the sizzle script
Add cranejs
enqueue crane.js
Crane wasn't being enqueued as it was lacking the prefix
