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
