Subject: Modified viewfunctions to split displayform, creating
 displayformstart and displayformend, to provide flexibility while still using
 the library. Also added support for hidden fields - including a common redir
 field. Removed redirectOnSuccess from controllerfunctions handle_form, and
 replaced it with the redir field. Removed redirectOnSuccess from controllers
 that used it and added handlecommandresults and redir entries to links and
 forms throughout many views. This will cause a redirect to the originating
 view when a form is successfully completed. acf_www-controller now includes
 orig_action in page_info to report the original action launched by the user.
