argument "obj" rather than "self".

Rewrote the basic section of the chapter on defining new types.
...
Changed the example to show how to create types the new way:
- Use a class new method rather than a new function.
- Use self->ob_type->tp_free in deallocators
- Use attribute descriptors rather than set/getattr methods.
- Make the type usable as a base type.
I split the example into 3 parts:
1. The minimal new type
2. Adding attributes and methods.
3. Finer control over attributes.
It's much simpler to define builtin types. These updates hopefully
show this.
I also made minor wording changes in two other places.
I still need to update xxobject.c

Move some of the longer example code to external fragments, and
...
include them using \verbatiminput. This has the advantage that pages
can still break at reasonable places, and examples that go longer than
a page won't get cut off.
Make a few small markup adjustments for consistency.
Explain that PyObject_New() is not a C function but a polymorphic
beast that returns a pointer to the type that's passed as the first
arg.
Explain why type objects use the PyObject_VAR_HEAD.
