[issue7444] Allow for a default method in the JSON decoder

New submission from Daniel Goldman <goldman.inbox at gmail.com>:
I encountered JavaScript-style Date objects in a JSON document that I
wanted to parse, and these objects were causing the Python JSON decoder
to raise an error with a message that said "Expecting object," followed
by the line and column numbers. Here is an example of how such an object
appeared in the document:
"someDate": new Date(1207568200000),
I went looking in the documentation for a way to plug in a "fall-back"
method, to be used when the module's standard conversion methods fail,
but none of the supplied hooks seemed appropriate.
It would be enormously helpful to provide a hook for such a method in
the JSON decoder in a future release of Python. I believe this would
parallel the JSON encoder's "default" keyword argument. In this way,
developers could provide their own method of handling non-standard
values in JSON documents.
Ultimately, to parse the Date objects, I created a function similar to
those in the json.decoder module, added the function to the
json.decoder.ANYTHING list, and assigned a new Scanner object with this
updated list to json.decoder.JSONScanner.
I couldn't find a similar issue in the issues list, but my apologies if
this has already been suggested.
