Made duplicate ID handling more efficient

Shouldn't create a new objectId each server run, by using a duplicateId
database that takes other things (such as planetcrc, templatecrc,
building, container, cell, coordinates)

Currently best solution I can see that doesn't consume a brand new lot
of 20,000 objectids each bootup.
