* Attempts to resolve the megaregion terrain edit rebound. 

* It does this by tweaking the throttles on child agent connection to a megaregion and multiplying the land throttle by 50.  (various bit and byte magic ensue)
* While, I doubt this will cause terrain crater sized potholes.. since it actually increases the bandwidth available for land in child regions when MegaRegions area active, more testing would be good.
* This, in theory, also shouldn't cause missing objects in child regions..    because all objects are in the root region anyway.   As I said, more testing would be good.
