Move the remaining legacy item template lookups to CObjectTemplate

Dev commands, BuildingManager, ChatManager, ForgeManager, NPCManager,
NPC, Warehouse, WorkOrder and ManageNPCMsg now call
CObjectTemplate.lookup instead of ItemTemplate.templates.get. Forge
production cost reads getItemResourceCosts(). Only the DB loader and
linkCacheTemplates still use the legacy class (removed in Task 1.8).

Removes the static_item_templates ParityCheck comparator. Final parity
(offline p17.py, 7586 rows): every id has a cache template, 0 item_type
differences, 0 item_resource_costs differences (84 ITEMs have costs).
