Added the possibility to edit the texture of the turrets head in the settings.
 (You can find head textures on this 
website. Choose a head then make sure to copy the (base64) value and paste it in the appropriate section of the settings menu, you may even create your own textures on websites such as 
Minecraft Skin Editor and you can get the base64 value using the 
custom heads generator).

Fixed holograms for turrets on previous versions that woud break the plugin.
