Incompatiblity when using with Panels' node edit page override

When using this module along with Panels (actually, along with the CTools page manager module) overriding the node edit page, the file node.pages.inc isn't being loaded. This is because CTools alters the menu callback which usually loads this file (node/%node/edit) and loads it later on in the context plugin file node_edit_form.inc.

I don't know who's to blame for this (either Merlin or Wim, I guess) but currently it's not possible to use AHAH_Helper from a CTools-overriden node edit page.

Possible simple solution: in AHAH_Helper, check if the current form is a node form and if so - include node.pages.inc.
