* Converts the block administration page to the fapi model.
    * Removes some 'type=markup' elements.
    * Adds a form_render($form['form_id']); in the theme function. Adding a form_render($form) just outputs an unthemed form. I suspect this is because of the heavy nesting of form elements and the rather dodgy array declaration, but I'm unsure.
    * Documentation/language fixes.
