Fixes for World Boss POIs on long running servers.

FIXED: world boss minions piling up after every restart

When the server restarted, or the area unloaded and loaded again, the world boss was picked back up but its minions were not. The next top up then saw no minions and spawned a full new set beside the old ones, so every restart added another ring of mobs. The minions standing there are now picked up along with the boss.

FIXED: dead minions counted for ever

A guardian or world boss kept the id of every minion it had ever spawned, dead or alive. Dead ones are now forgotten, but only while the whole area is loaded, so a minion that is simply in an unloaded chunk is not mistaken for dead and replaced.

FIXED: minions spawning while the area was half loaded

With a player at the edge of a POI, part of it can be loaded and part not. The minions in the unloaded part could not be seen, so more were spawned. Guardians and world bosses now wait until the whole area is loaded before topping up.

FIXED: world bosses with a big radius never rising

To raise a world boss with nobody near, the mod loaded only the one chunk the POI sits in. Any radius bigger than about two chunks needed more than that, so the boss waited 30 seconds, gave up, and tried again a second later, for ever. The whole area is now loaded while the boss is raised, and released again once it stands. If the area still will not load, it waits a minute before trying again instead of looping.

Thanks to Xmat5 for the report and the suggested fixes.
