The User Edit screen could have more classes on the HTML

[simonwheatley]

Given a more liberal sprinkling of classes through the WP admin interface, plugins could highlight different areas, hide unwanted form fields easily, etc. Currently you have to use something like jQuery in order to find and address fields that you want to hide.

The attached patch adds lots of semantically appropriate classes to the user edit screen, so plugin authors of the future can use CSS rather than resorting to Javascript. The patch is created against 2.6.2.
