Cleanup inventories from deleted worlds

It would be useful if PerWorldInventory had a cleanup command to delete the inventories associated with deleted worlds. Ideally, it would automatically figure out which files were unnecessary based on which worlds are currently loaded. Doing it automatically would be especially good since it removes the possibility of stupid mistakes. It could take into account share settings and whether gamemodes are split. For example, if gamemodes aren't split, it would delete any files associated with a particular gamemode. It's obviously not a critical feature. Maybe it's just something to consider for the 2.0 rewrite, but I thought I would throw it out there.

Thanks.
