Rewrote this stuff so that it is all multiple object oriented instead of looping single objects... The way it is written, there should be no speed decrease (and in some places, a speed increase) and maybe a miniscule amount of extra memory used in the move_topics function... Everything in there should be O(n) where n is the number of topics or posts being delete or moved or whatever. Multiple topic insertions are not supported as I cannot forsee where one would like to insert multiple topics into the same forum. Different forums I can understand but there is no way to optimize that _at all_. More work to come...
