Partial port of Avination's support for the new physics parameters.

Implements the parameters as properties, the serialization and
database storage (MySQL only). Implements llSetPrimitiveParams for
prim physics shape and the other 4 extra params. Only the prim shape type
"None" is currently functional. No support for the Viewer UI (yet), that
will be ported in due course. Lots more to port, this is a large-ish changeset.
