Add more logic when document.documentMode is undefined.
In IE version < 8, document.documentMode is undefined, so attempt to use document.compatMode to see if we are in standards mode.
If we are in standards mode, treat the browser version as the document mode.
Otherwise, IE is emulating IE 5. For instance, in quirks mode, IE8 and IE9 both report a document mode of 5.

Start using DOMTokenList methods in dom.classes.  See http://caniuse.com/classlist.  Added implementations for has, contains, get, swap, enable, toggle.  Support for add(), remove() and addRemove() will be tricky for a couple reasons:

- browsers don't seem to support the var-arg versions here: http://dom.spec.whatwg.org/#domtokenlist
- Closure allows space-separated class names, DOMTokenList throws exceptions for invalid classnames

All classes unit tests pass in Chrome, Firefox and all versions of IE.
