Normalizing the `text-transform` default value on select and button nodes.

I ran into this one the other day and thought it was a good fit for this project.  Certain browsers declare default `text-transform` values for `button` and `select` in their user agent stylesheets and certain browsers don't.

The easiest way to see this is comparing WebKit vs. Gecko vs. Trident with this fiddle - http://jsfiddle.net/tj_vantoll/dUjXB/11/.

I wrote up a more thorough explanation of what I've found on my blog - http://tjvantoll.com/2012/07/10/default-browser-handling-of-the-css-text-transform-property/.
