Issue 3744 - Fixes capitlization of uses of Tos and Faq to TOS and FAQ

http://code.google.com/p/otwarchive/issues/detail?id=3744

Simple, but effective.

Shouldn't effect work titles, should effect future pages created.
Can't make edge case guarantees, for example - if AO3 decided it would be a great idea to include a new search feature called "Fruc-Tose  Searcher" (Fructose would be fine) then it will make it "Fruc-TOSe Searcher" but seriously the odds of running into these is just too small to be of concern.
