Tweaks and more

FIXES:

• A Vending Machine in Server mode will "void" items given by players for a trade. Prior to this change the items would be placed into the inventory.
• Machines placed prior to v0.3.9.x may not be rotatable using a wrench because of invalid facing data. Logic now detects when this happens and forces to a valid facing.

CHANGES:

• Transport pipes no longer connect to Vending Machines. This behavior can be changed by modifying the configuration file.
• Worms can be fed to chickens. This will cause 0-3 eggs to spawn around the chicken.
• If there aren't enough items in a Vending Machine inventory to complete a trade the ItemStack rendered in the Vending Machine entity will have a quantity color coded in RED.
• When a magic item is scrapped Bottles of Enchanting are added as part of the output component list. The number of bottles added is dependent on the quantity and quality of enchants on the item.
