CSS cleanup: dynamic rules tab (My rules)

For comparison, before: http://chrisly.me/image/1g01441z0F2c

and after: http://chrisly.me/image/1v160U0P2i07

Also:

* give good class names to some element in dyna-rules.html
* select the ul more generically in dyna-rules.js (since a container was added)
