load threading option if threading enabled. (xml_encode): write out

2004-05-12  Not Zed  <NotZed@Ximian.com>

        * filter-rule.c (xml_decode): load threading option if threading
        enabled.
        (xml_encode): write out threading setting.
        (rule_copy): copy threading option.
        (rule_eq): compare threading.
        (build_code): build the match-threads stuff if set.
        (fr_grouping_changed): insead of the match_all match_any activate
        clalbacks.
        (fr_threading_changed): handle threading option menu

        * rule-context.c (rule_context_init): set capabilities flags.

        * vfolder-context.c (vfolder_context_init): set capabilities flags
        to include threading.

        * rule-context.h: added a capabilities flag, grouping and
        threading capabilities.  Sort of a hack to workaround not being
        able to put grouping or threading into rules.

        * filter-rule.h: added an option for threading as well as
        grouping.
