Update to Cosmetics Crate & keys

Hey all!
Tonight I've made some updates to the cosmetics crate, and all keys!

The cosmetic crate still gives out the same range of hats, but now you can right click with them whilst they're in your hand in order to put them on! So now you don't even need to be a peasant! If you have the old hats, Fred and I would be more than happy to replace them for you!

And then finally I've updated keys to no longer say "Use /crates to redeem". If you have stored keys, they will NO LONGER WORK. Please ask us to replace them!

Cheers! ?
