Subject: Adds an optional module to enforce prim limits on a given parcel
Takes into account acculmitive prim allowance when multiple parcels are owned
by the same avatar on the same region. Does not handle prims that are moved
by a script or account for temporary objects at the time of creation. other
wise handles all tested cases including: Creating a new object from the build
menu Moving an object from another parcel duplicating an object via shift
move rezing an object from a script
