Garbage collection

There needs to be some system for removing surplus items, rest products and garbage from the game world. Otherwise the server will eventually get overburdened with items. Randomly picking away items that the players might carry around or use is not a good idea though. The garbage collection should not happen unlogically, it should seem natural in the game. Some ideas for ways to do it are listed below. Probably it will be best to use a combination of many methods.
