Pizza Palace Update

While I was able to use the Can 'O Beans code for the pick up and consumption mechanics, in order to transfer ingredients to the counter and stove, I had to add a fair bit of code. 

I added code to allow for ingredients to be placed in order on the counter and turned into a singular pizza. As well as for the uncooked pizza to be placed in the oven, cooked, and either removed from the oven or burnt.

I added code for the cooked pizza to be served to a customer.

I modified code from the key/door mechanic to make the door openable after all the customers have been served.

All of this was necessary to make a basic pizza shop game.

Additionally, I added models for the pizza, pizza ingredients, ingredient spawners, counter, oven, and customer.
