Better handling and grouping of Guest Beers
Guest beers (i.e. other breweries' beers that you buy in and sell in addition to your own range) are now handled better. You can now create a "Guest beer" in Breww, which is much like a normal beer, but you never brew it yourself. Guest beer stock items can then be associated with this "beer" (and a container type). This allows them to be grouped together in the display around Breww and on the Trade Store.
