Changes between Initial Version and Version 1 of Ticket #222

16	16	The requirement for the reaper is based on the assumption that entities are killed fairly high on the call stack, and the calling functions may still be wanting to do something with the entity. To detect when an entity is dead, we are already using an isDead flag. I figure this could be replaced with the standard weak_ptr isValid mechanism.

18		Finally, the network ID. For practically limitless numbers of entities, we need a 32-bit counter that resets to zero each game. Entities store their number (which is what is serialized), and ~~EntityMan~~ger needs a sparse mapping of ID -> HEntity (the new/old entity reference system).

20	20	This sounds like it would simplify things; a partial implementation is underway, but a few design questions remain to be hashed out (Philip and I will be discussing this shortly; any other input is welcome).
