*** Some major differences between 1.3 and 1.2 ***

- A number of structure element names have been changed for brevity and to make
  them more logical: -

  1 In object structure barrier[] and patrol[] have been changed to
    bar[] and pat[] respectively to make npc set up code less long winded.

  2 In object and user structures user_victim and npc_victim have changed to
    user_oppnt and npc_oppnt (short for opponent).

- The parser is no longer case sensitive as far as object names are concerned.

- The command "unstatue" has been added since previously the only way you
  could remove a statue spell was the heal the person which may have been
  undesirable in some cases.

- The output from the "status", "detail", "who" and "system" commands have 
  been made tidier.
