This update for thunar-vcs-plugin fixes the following issues:

Update to 0.4.0:

  Meson has been added as a build system in this release, and the
  associated archive has been generated by 'meson dist'. Although
  autotools has been retained for the time being and can still be used
  via 'autogen.sh', meson is now the preferred build system, and
  autotools will be removed in a future release.
