Classifieds subsection for tandem gear

[piisfish 140]

I suggest adding a subsection for Tandem Gear as it's pretty uneasy to find the ads in the middle of all the rest.

I've added a category for tandem gear... And moved a few tandem items into it. I'm assuming the tandem items remain few and far between and the fact that they aren't categorized by type of item inside the tandem section shouldn't really create a problem and still be easier to locate than if they were mixed in with the others like before?
