New Jeff costume and a vendor on Gay Island

Okay, aside from the new costume, I kind of think we're in need of a vendor in Gay Island...Especially if you're me who wasted all her coins/potions getting through those spike pit jumping puzzles in the VoL spider cave. Eek!

I put Leslie the Travelling Sales-bian on that one up-high area, and her stock is identical to Juan's. I don't want to tinker too much with code.
