Add tags_vn_direct cache table
This speeds up VN pages a little bit, but the main reason for this table is to implement no-parent-inherit tag search. Because the rows in tags_vn_direct represent an intermediate calculation for tags_vn_inherit, generating and updating these caches isn't all that much slower with this change. I'm not a fan of the DELETE & re-INSERT approach on individual-VN updates, though, as that tends to cause unnecessary (index) writes. Not sure how complex a more incremental update is to implement, but it sounds painful. :/
