* Almost all tags are now UserTag definitions. The only exceptions
	  are:

		and bounce goto if label or unless

    * New TagDir directive (default is VENDROOT/code) sets the
	  directory (or directories) which are searched for code definitions
	  set by UserTag and CodeDef.

	* New TagGroup directive establishes groups of ITL tags which can
	  be included.

	  	TagGroup :crufty "banner default ecml html_table onfly sql"

	  The default groups include :core, which contains all of the
	  ITL tags defined in 4.8/early 4.9. The groups are defined
	  in $Vend::Cfg::StdTags and can be undefined if desired
	  with "TagGroup :group".

	* New TagInclude directive allows inclusion of tags (or groups
	  of tags). If a tag is defined as a core tag (with a .coretag
	  or .tag or .ct extension) and is not included, it will not
	  be compiled and placed in the tag map. This is for all catalogs,
	  so if *any* catalog uses a tag it must be included.

	  Examples:

		# Include the base tags
	  	TagInclude :core

		# Not the commerce tags
		TagInclude !:commerce

		# But make sure item-list is included even though
		# it is in :commerce
		TagInclude item-list

		## Double negatives are honored
		TagGroup    :foo "bar !baz buz"
		## With the group above, the below is equivalent
		## to TagInclude !bar baz !buz
		TagInclude !:foo

    * New CodeDef directive allows the setting of filters,
	  order checks, FormAction, ActionMap, ItemAction,
	  and LocaleChange.

			## filters
			CodeDef  mixedcase Filter
			CodeDef  mixedcase Routine <<EOR
			sub {
				my $val = shift;
				## [filter mixedcase]mixed case[/filter]
				## outputs "MiXeD CaSe"
				$val =~ s/(.)(.)/\u$1\l$2/g;
				return $val;
			}
			EOR

			## order checks
			CodeDef  mixedcase OrderCheck
			CodeDef  foo  Routine <<EOR
			sub {
				my ($ref, $var, $val) = @_;
				return (1,$var) if $val eq 'bar';
				return (0,$var, "foo must be bar");
			}
			EOR

	   All work in catalog.cfg; LocaleChange and ItemAction are not
	   global. FormAction, ActionMap, and ItemAction directives
	   are equivalent to their CodeDef equivalents.
