* New command 'WIKI history|<pagename>' to list the revision history for a wiki page.

* History format has changed again -- delete any experimental wiki rooms you have created.  The memo field now contains a UUID for each edit, which we will use for identifying revisions because the MIME part numbers will change with each edit.  Also moved the timestamp into the second field position, followed by the username and nodename.  No longer saving the user's Internet email address.
