Added new_request to the documentation, and documented that with both edit_request and new_request, you just need to set the values as local variables, and ad_form will suck the values into the form. Then added the code for new_request to suck the values into the form.
Changed code to use the new fs::get_folder_objects rather thanfs::get_folder_contents because the code only needs object_ids and thelatter proc does all sorts of permission checking and the like.
