New FAQ page - dodgy agencies

Because these issues get dredged up very often, I've added a new FAQ page with a list of threads discussing the most notorious agencies. I'm sure there are more that I haven't added, but those were the ones I could remember. You will find the new page here: http://www.theatre.asn.au/book_page/dodgy_agencies_previous_discussions_on_who_to_avoid This is in the hopes that people won't start new threads retreading old ground, as well as to have easy to find links to old threads that have lots of useful info.
