    build: improve project() call
    
    - There is a plugin written in Vala.
    - The license information was not 100% correct, it should have been
      GPL2+. It was anyway not used anywhere (with meson.project_license()).
      I prefer to not duplicate the license information a bit everywhere,
      otherwise it takes more time when changing it. There is already the
      COPYING file.
    - '>= 0.49' looks cleaner :-)
