Subject: Mantis#1707. Thank you, Melanie for a patch that: This patch limits
 the maximum size of prims that can be created using libsl bots or modified
 clients to 65536mper side. It also limits LSL functions to that size. If a
 prim is already physical, the enforced constraint is 10m. A prim that is
 larger than 10m cannot be turned physical, either via script or UI. Linksets
 are handled correctly, so scaling of physical linksets is constrained by the
 size of it's largest component prim. Also, turning linksets physical is based
 on the size of it's largest ptim.
