function webform_pre_render_remove_id in Webform 7.4

A Form API #pre_render function that removes the ID from an element.

Drupal forcibly adds IDs to all form elements, including those that do not need them for any reason, such as the actions wrapper or submit buttons. We use this process function wherever we wish to remove an ID from an element. Because #states and #ajax require IDs, they are only removed if the states and ajax arrays are empty.
