Topic: skin_fang(s) to flesh_fang BUR

The bulk update request #13736 is pending approval.

create alias skin_fangs (4) -> flesh_fang (1532)
create alias skin_fang (143) -> flesh_fang (1532)

Reason: All these tags mean the same thing and are used for the same purpose, and should be condensed into one tag.

Of the three, flesh_fang is the only one who has a wiki that's sufficiently fleshed out, hehe.
