Refuse DB writes for static world objects

DbManager.refuseStaticWrite logs the handler method and its caller and
stops the write (W3). It guards every write whose row belongs to a
Building, Zone, City, Guild, Mob or NPC: 69 handler methods, including
friends/condemned/patrol lists, guard minions, NPC profits and guild
banish/alliance lists. ID-only methods look the object up in the cache.
Writes that only reference a static object (character guild history,
another guild's alliance row) are not guarded.

Value changes: none; nothing is flagged static yet.
