MiningBoxes | Must needed plugin for a unique prison experie

Edited it all to work with the latest version of Bensku SKRIPT - Completely recoded the whole ADD ITEM GUI. - It will now show you what is in the box in the GUI - You can now remove items by clicking on the item you want removed in the GUI. - Optimised the mining blocks lag to the maximum. (Cut out 15 lines of unneeded code that made it laggy than this version) - Added message to when you save box chance - Fixed issue where beacons/chests and openable blocks can't be used as miningboxes - MiningBoxes are now block based over region based. (There is a option in the skript where you can put what blocks you want people to find miningboxes in) So you can now use MiningBoxes in any server type!
