Added in support for auto-incrementing build numbers into the build script (and code). A nicer way to track what version folks have :)
Added Alchemical bag inventory and functionality(not completely finished). Also made the bag be able to share its contents with a connected alchemical chest. 
To link a bag to a chest shift right click with the bag in hand on the desired chest. To open the sharing menu after the bag has been linked just shift right click with the bag in hand.
