  To save memory we will share these actions between links, and just store
  a pointer to it in the style run.

  Some of them can get fairly long, eg:

  Action - send to MUD: "Wear #24850|look #24850|examine #24850|
                         drop #24850~Wear The Curse of Kral|

                         Drop The Curse of Kral"

  ... and then the above may be repeated for every *character* of the hyperlink
      if they are in different colours.

  Now, assuming that you go to the same rooms more than once, or look at your
  inventory more than once, such items will be cached, by being stored once in the
  CAction list. I use a reference count to know if we can ever get rid of one.
