Subject: New file - lists rules appropriate for vfolders (no actions, etc).

2000-05-27  Not Zed  <NotZed@HelixCode.com>

        * vfoldertypes.xml: New file - lists rules appropriate for
        vfolders (no actions, etc).

        * Makefile.am (EXTRA_DIST): Add vfoldertypes.xml

        * filter-driver.c (filter_driver_expand_option): Made public from
        expand_filter_option.
        (filter_driver_rule_count): find out how many user rules are
        defined.
        (filter_driver_rule_get): Get a user rule by index.
