+ Fixed sellhead throwing an error if you have a normal skull in your inventory at the same time
+ Some messages in messages.yml have been made redundant
+ Further debug work
+ Added some new messages
+ Update checker is now friendly to the website using it
+ Fixed crafting.yml not loading (I panicked too)

I'm aware textures for crafting are not working, I have tried a lot but it's stressful to do, especially with conditions I've been facing recently. Thanks in advance.
