Added support for multiple inheritance. Not as hard as I feared.

Apply operator features to both the operator name, and the renamed
"__*__" method.  That's the only way to hit all corners.

Added support for %pythonnondynamic.  I believe this implementation
is more correct than the existing implementation, but I'm still
waiting for an adjudication on the behavior of the python_nondynamic
test.

Current list of unsupported features that require minor tweaks
to the test suite:

- 'this' member variable is obsolete.

- No support for reversible operator overloads (e.g., __radd__).  You
can still support this:

a = MyString("foo")
b = "bar"
c = a + b

... but you can't do this:

a = "foo"
b = MyString("bar")
c = a + b

With the tweaks, the test suite now fails on python_nondynamic.
