INCOMPATIBLE CHANGES: I'd like to have none of these, but hey, this *is*
      pre-alpha.  I try to make everything backwards compatible, but for
      the more obscure stuff, I figure it's not worth it.  If a change I
      make really puts you out, please let me know, and maybe I'll try to
      make the old way work out after all.

0.44: - no more gui_mode_configuration_disabled or gui_mode_ignore_disabled
      - using the "gui_mode_config_savelocal" option will not recognize local
        modifications made from earlier versions of log_analysis.  Be careful!

0.42: - dests may no longer contain backslash

0.38: - date_format defaults to %Y_%m_%d
      - -o no longer also outputs to standard out.  Add -O for the old behavior.
      - config_version is now mandatory

0.37: - replaced end directive with @@end.  end will give a warning.
      - the default sort is "funky" (understands IP addresses) instead of
        a string sort.

0.36: - -D has been renamed to -I evals.  
      - -F has been renamed to -I internal_config

0.35: - No more support for the (formerly optional) 4th field of raw_rules, 
        ie. the code hook.  If anyone had a real need for it, contact me.

0.34: - Discontinuing support for required_log_files in the config, because 
        some internal stuff was assuming it could modify required_log_files.

0.29: - Directives using "-" instead of "_" have been changed to use "_".
        These include include_dir, include_dir_if_exists, include_if_exists,
	and block_comment.
