SU Addon - Silk Spawners

This mod is an addon to ServerUtilities (Can be found HERE). 

It adds the ability to harvest and place spawners based on the config.
When the mod is started up it will create config files for every mob in the game. Ender Dragon and Wither included.
You can delete which ever spawners you don't want to use or don't want the player to pickup.

For most of the spawners the player won't have access to them since they don't exist in the world. 
The spawners that do spawn (zombie, skeleton, blaze, etc), if the player has the permission: "serverutils.spawners.pickup" and they have the Silk Touch enchantment on their pickaxe, then they can break it and pick it up.
If the player has silk touch on thier pick but doesn't have the perm to pick up the spawner they will be sent a message telling them that they can't pick it up and if they still want to break it to crouch and break it.

This was added to prevent players from destroying a spawner by mistake.

However, the spawners that don't exist in the world will be needed to be given to them or placed in the world for them to be able to use.
This can be done with the /spawner command added by this mod. 

There will be a page on my wiki to further explain this and how to configure everything. 
When I get it added I will update it here.

The config folder can be found in "config/serverutils/spawners/"
Here are a few example configs:

Dragon.json
Greeter.json

The Greeter file has more configurations and shows how you can add villager information.
Currently you can't set up the trades that it will have however.
