Fix #384 group encounter mob loot

Adding a new column to the spawn table:
alter table spawn add column loot_drop_type int(10) unsigned not null default 0;

- loot_drop_type of 0 means spawn will when part of an encounter transfer its loot to the next alive spawn.
- loot_drop_type of 1 means the spawn will drop its own loot when it dies (like a named mob ideally).
- These changes do not change body drops which remain on the spawn/npc that dies, not transferred.
- loot and chest drops have been expanded beyond NPC's which means potential PVP support or even other types of spawns can drop loot/chests (probably expand loot_drop_type at a later time for more options in this area).  Need lua interface support (when player dies and all that) issue #436 opened for it.
- some additional mutex lock protections on spawn loot
- SetLootTier(loot_tier) and GetLootTier(), SetLootDropType(drop_type) and GetLootDropType() added to lua
