multiple fixes for lists:

- modify results-template_2 to handle "more results" for user
  lists. note it wants "more" and not "more_results" for this var
  because this is also used by search results pagination and needs
  different onclick actions depending on whether it's from a
  search or a list.
- cleaned up mylists-template and added a "delete" button (so
  users can delete their lists) with confirmation pause. (the
  function on the end of this isn't done yet, but will be.)
- modified showitemlist to handle "data.more" to introduce
  pagination for user lists.
- added nextItemListPage() to display subsequent pages of item
  lists, a-la loadmore().
- removed the openForm() from refresh_acctinfo() when receiving
  a 302 because it was opening and then closing (there were
  overlapping openForm()s which were both triggering because it
  happens so fast, the .is() was evaling the same both times.)
