Editing by permission only

Would it be possible to change the plugin to use permission only for editing the shop? 

Already had one of my mods delete items from the shop because they didn't know what they were doing. And it's easy to do this if you aren't paying attention. I've trained myself to not click the red x unless that's what I actually want. But I don't really trust my mods to always remember that since a red is is usually your way out of a menu.

Basically I want to be the only one on the server that can edit the shop. There's one other actual admin. But I don't want them getting into the editing menu either.

Changed Status from Pending to Closed
