The start of objects, in object.ops

I've decided part of the implementation for objects, and started in
on the ops for them. Right now it's just a sketch, but the following
ops are going in:

newclass Px, Sy

Creates a new, standalone class named Sy, class PMC put in Px.

subclass Px, [SPy], [Sz]

Subclass $2, and put the new subclass PMC in $1, If $3 is specified
(it's optional) it'll be the name of the new subclass, otherwise an
anonymous subclass is created.

singleton Px

Takes the object in Px and puts it in its own anonymous subclass of
its current class.

class Px, Py

Gets the class PMC for the class in $2, puts it in $1

classname Sx, Py

Gets the name of the class in $2 puts it in $1.

This is hardly sufficient, of course, for a full implementation, but
it seems a good place to start.
