village shops

I think villages over all are good but they lack some basic things that all towns have.  So I think the shop is a great addition.  Now, I know what you are thinking, we already have trading and I know that, but shops sell all kinds of things but for a higher price of course.  Emeralds are the price by the way.  You can buy stuff like lower level armor, ingots, tools and weapons, etc.  You can also sell un-wanted items so you don't waste anything.  Of course you can not sell trash like dirt blocks.
