Form styles are dependent on markup

[corroded]

HI just wanted to comment that some of us don't actually use divs for forms(formtastic, etc) and it would probably be a good idea to make them markup independent? By default we have div.input, but it would be better if it was just plain .input, so we can also apply that to <li>s for example.

Is this a good path to take? If so I can probably help out with this :)

Don't over qualify elements

Yeah, overqualifying is bad. Removing the div from div.input in 1.3-wip branch right now. Will now just be form .input so that it is at least scoped to the form styles.

We can revisit changing the form markup in v2.0 since that'd change a lot of markup and classes, but for now in the default form styles the .input has to stay. It's also worth noting that the .input div does not exist in the stacked forms. You can use that if you like.
