Marketplace tweaks

I don't expect major changes, but there are a few things I would greatly appreciate.

1. Allow a toggle switch to only show Male or Female items.

2. Add a sort by time listed button.

If I can sort by time listed, I wouldn't have to scan the entire list everytime I look.

Nice suggestions that have been discussed in the past, but not recently. It's always good to bring these topics back up to show that we are still interested.

Fixed!

I completely agree that old threads that are relevant should be bumped, but there seems to be a fear of being flamed with "Necro!" for that.  I'll leave before it gets more off-topic.
