update to 2.2.4

ArX-2.2.4 2005-Nov-16

"merge" now uses a three-way merge by default, with support for
external merge tools.  "merge" also now takes the --update option
instead of using heuristics.

"merge", "dopatch", and "replay" now record when \ 
there are conflicts
in the tree, and "commit" will refuse to act unless they are cleaned
up with "resolve".

The --silent, --quiet, --default-output, --report, and --verbose
options have been replaced with -v and -q options.

ArX is now much more clever when dealing with renames.

"commit" and "tag" now support --author and --date options.

The patch queue manager has been updated.

Some bugs when working across filesystems have been fixed.
