css *usually* returns the default value (not undefined). Certain rules in the list (like `fontSizeAdjust`) seem to return null at least in Chrome, but setting that doesn't seem to hurt anything. Typically for things not set, they will just end up equaling each other with things like `normal` or `none` or `0px` so the existing logic should catch this. I'll go ahead and change it to !== to prevent any accidental type coercion though.

I'm really liking not having to specify the extra selector though. It will make it easy to drop in to a site. The demo is really cleaning up too: https://github.com/bgrins/ExpandingTextareas/commit/3555f65794114b9efe0a5227bcbbf45106f17962.
