Fix registered_items oddity and add check for unknown nodes.

Browse Source 
* Mobs redo uses `registered_items[]` where clearly the proper table
  accessed should be `registered_nodes[]`.  Perhaps this magically
  works, but it looks nonsensical.  Switch to the use the more
  sensible `registered_nodes[]` table.
* Check if node has a definition table before attempting to evaluate its
  attributes.
* Define local variable to cache multiple accesses to `registered_nodes[]`
  and improve readability.
