[Docstring-develop] pydps - name/value annotation added

As ever:

	http://www.tibsnjoan.co.uk/reST/pydps.tgz

This lunchtime's work is to change how names are handled, such that the
HTML can report on what a name is *set to*. This is (obviously!) limited
in usefulness, and can only be done if the name is assigned to exactly
once at the particular level it "belongs to". Amendment by methods and
functions will, of course, not be seen.

Look at html/html.py for an example of what this looks like.

It *can* be misleading, as if one does::

    a = 1
    b = a
    a = 2
    c = a

you will get "a" reported with no value (since it has more than one
assignment), but "b" and "c" both reported as being assigned "a",
despite the fact their values are different. It may be that more of the
reports need suppressing.

On the other hand, if one is doing::

    def __init__(self):
        self.postfix = 0

then being told that "self.postfix = 0" is quite useful...

(and yes, I *know* I'm reporting names in places that DPS doesn't want
me to, but information suppression isn't coded yet)

(note for anyone reading the code (yuck) that the *old* method is still
in there as well, and also that the *gathering* of this information is,
erm, rather inefficient since it's done by yet another scan of the AST)
