Added the ability to use textures for graveHeadSkin. By default the plugin will use a grave texture now, not a chest. The plugin is called Graves after all. I changed the colors of the plugin from gold to gray to match the new grave. If you want this new look it would be best to reset your config. Or you can keep using the old one fine!

Fixed players being able to shift click an item into the Graves GUI and losing it.

Fixed zombies spawning even when set to false.
