Hector Franqui 3df43ab580 Spawner: Assign sits, furnaces and storage nodes to spawned NPCs.
Small basic schedule change: NPCs now sit from 12-1 on whatever sit they 'own'.
Fixed /restore_plotmarkers not clearing all metadata.
NPC: Attempted to add a fix for the children growing on their own (due to mobs_redo).

-- In addition, the NPCs need to know where some places are, and know
-- where there are nodes they can use. For example, they need to know where the
-- chest they use is located, both to walk to it and to use it. They also need
-- to know where the farm they work is located, or where the bed they sleep is.
-- Other mods have to be supported for this to work correctly, as there are
-- many sitting nodes, many beds, many tables, chests, etc. For now, by default,
-- support for default MTG games and cottages mod is going to be provided.
