Added BeverageDrink Model

This is the model that will link the beverage and drink models
together so that the user can add beverages to their drinks. I
still need to create the methods on Drink and Beverage that will
get the ingridients.
Added application class

We will be storing global variables here so we need to define
a place where we are able to store them.
Added bluetooth and other stuff

Opps I didn't commit this back when I wrote it :(
