Update to 1.30

Upstream changes:
2019-09-17      version 1.30
         Fix after 10 years.
         1. 12-cache.t: Fixed so that it works on MS-Win32.  I forgot to
            issue binmode when copying the MO files.
         2. 00-signature.t: Removed TEST_SIGNATURE, as this does not work
            on everybody who does not have my GPG public key, but me.
         3. 03-errors.t: Removed the debugging output.

2019-09-09      version 1.29
         Fix after 10 years.
         1. Gettext.pm: Added support to purge the lexicon cache and
            reread the MO file on calling textdomain() when MO file is
            updated automatically.  This enables MO file live update with
            persistant applications like Mojolicious or mod_perl.
         2. Source is now on Github.  See:
