Remove tagged_is_strict option, and just behave as though it was enabled

Jon was worried about the backwards-compatibility break involved in making
tagged() not match non-tag links, but Joey seems less concerned about it.

 > And this is an illustration why a clean work-around (without changing the software) is not possible: while thinking about [[todo/matching_different_kinds_of_links]], I thought one could work around the problem by simply explicitly including the kind of the relation into the link target (like the tagbase in tags), and by having a separate page without the "tagbase" to link to when one wants simply to refer to the tag without tagging. But this won't work: one has to at least once refer to the real tag page if one wants to talk about it, and this reference will count as tagging (unwanted). --Ivan Z.
