Beverage

Beverage is a CategoryFlag used to signify that the material is intended to be a beverage - that is to say, a drink intended for casual consumption rather than the more practical fluids found in bottles such as healing liquid.
The practical application of this flag is that having a bottle filled with a beverage causes alcoholic characters to ask for it if the player chats with them. Giving an alcoholic character a beverage results in them immediately consuming it, unless they are otherwise occupied (e.g. fighting, patrolling)
