This adds visual differences to the sprites of many of the game's drinks when they are opened, as well as visual fill levels for most see-through drink containers. Condiment packets are visibly torn open in the corner when opened. Glue, lube, and condiment bottles are visibly opened too. I also noticed that the soda bottles were all completely opaque, so I fixed that while I was at it. Oh, and I updated the wine bottle sprite to say 14 instead of 13, 'cause yeah.
As a result of the way fill levels take on the color of the contained liquid, many of the drinks have changed slightly in appearance. This can be adjusted in the future by modifying the colors of the reagents, but seems outside the scope of this already large PR. This also means that if you refill the bottles with a different liquid, they'll take on the new color appropriately.
