Disposal Blocks

Simple set of commands that will allow the setting of blocks as disposal blocks, which will clear their inventory upon closing. As per the request I'm filling, the functionality is only available with chests and dispensers.

This plugin is intended for those who have an excess of items, but may not have access to lava/another easy way to dispose of them. Instead of potential lag causers such as lava, or excess item entities, this disposes of the items simply, and with no lag what-so-ever.
Commands:

• /dd create: Designates the block that's next right-clicked as a disposal block.
  
• /dd remove: Removes the disposal block functionality from the block that's next right-clicked.
  

Permissions:

• dd.create: Gives access to /dd create.
  
• dd.remove: Gives access to /dd remove.
  
• dd.break: Players with this permission can break disposal blocks.
  
  All permissions default to OP.
