Title:
  immediately after opening a v2.1 file, deleting a node causes an
  exception

Status in HypeDyn:
  Fix Released

Bug description:
  Immediately after opening a v2.1 file, deleting a node causes an
  exception to be thrown. For example, open the v2.1 version of
  LRRH4.dyn, then delete "Go directly to Grandma's house":

  Exception in thread "AWT-EventQueue-0" Argument #1 '(assert 374)' to 'car' has wrong type (String) (java.lang.String cannot be cast to gnu.lists.Pair)

  I think the old-format actions are still in the data table, and its
  trying to go through them and check for "follow link to" actions that
  point to this node to delete them. When it hits an old-format action,
  which is stored as a string rather than an s-expression, it chokes.
  Probably should delete the old entries from the data table after doing
  the conversion to v2.2.
