Clean-up, delint, performance

[joelpittet]

This may look unwieldy but it's not terribly exhaustive clean-up.

• Delinted most of the JavaScript.
• Wrapped the JS in a closure for better no-conflict support.
• Made all tabs spacing into 2 spaces for consistency.
• Removed a few overqualified CSS selectors (May be better to BEMize these to avoid conflicts)
• Commented out the CSS generic table styles, probably should move that to a different CSS for the demo presentation only?
• Moved the events to the bottom of the JS.
• Made the function declarations use all the same declaration style.
