Update pwgen to 2.04.

Update pwgen to 2.04.

Changes since 2.03:
        * pw_phonemes.c (pw_phonemes): Allow one or more capital letters
                and one or more digits in the generated passwords.
                (Addresses Debian Bug: #182595)

        * pwgen.1: Explain that human-memorable passwords are vulnerable
                to off-line brute force attacks.  (Addresses Debian Bug:
                #276976)

        * pwgen.c, pwgen.h, pw_rand.c, pwgen.1: Make -A and -0 aliases to
                --no-capitalize and --no-numerals, and make those options
                work when --secure is specified.

        * pwgen.c, pwgen.h, pw_rand.c, pw_phonemes.c, pwgen.c: Add support
                for the --symbols/-y option, which adds special characters
                to the generated password.  (Addresses Debian Bug: #154561)

        * pwgen.c: Add -H, --sha1 option, to allow computing reproducible
                passwords, given a known file, and a known seed.
                (ie: pwgen -H ~/my_favourite.mp3#olivier@guerrier.com gives me
                a list of possibles passwords for my pop3 account, and I can
                ask this list again and again).   Feature suggested and
                implemented by Olivier Guerrier <olivier@guerrier.com>.

        * Fix obvious spelling typo in pwgen.1.  (Addresses Debian Bug
                #311461)
