[twill] basic auth & file upload.

[Titus Brown]

Hi, Chris,

-> I think my biggest requirements at this point are:
-> 
-> a) Handle file uploads (<input type="file">);

This is now implemented: 'formfile' command.

-> b) Handle HTTP basic auth username/passwords

Also implemented: 'add_auth' command.

Both available in

	http://darcs.idyll.org/~t/projects/twill-latest.tar.gz

I'm prepping for a 0.7.1 release; if anyone has any more issues or
concerns, now is the time to mention them!

cheers,
