Whichever function calls this one is currently responsible for making sure the conf_menu_entry is already set up properly and everything that calls this function currently either allocs a fresh menu entry or provides one that is NULLED out in advance.

Oh wait, nevermind.  I see now that I changed this from a memcpy to a strcpy and a LIST init.  Should be fine.

This is probably for the best for a couple reasons though. For instance, the CONFBRIDGE function can modify the contents of the datastore allocated menu while the user is still in the conference if it is set via AMI. We probably don't want the menu to be modified in place during this time (even if it would be cool to be able to edit a menu while the conference is in progress).
