Fixed a bug in hook_menu which was causing an Arrange Fields tab to

 appear on all nodes for users with the administer arrange fields
 permission AND webform module installed.

 Also, added a hack which forces Captcha to not be treated as a
 fieldset.  This seems to be the default behavior for most people,
 but an issue was raised where, for some reason, Captcha was being
 treated differently, and it caused an issue with Arrange Fields.
