This mostly defines a new KVC interface on NSObject. The major difference
to KVC is, that KVC calls method keys while SoObjectLookup returns an
invocation object.
It also introduces a new "class" hierachy used for "web" methods and classes
that basically mirrors the Python object system (where ivars and methods are
both "attributes").
