v0.7.0

• Add DISCID_USE_HTTPS build flag: If set, the functions discid_get_submission_url
  and discid_get_webservice_url will generate URLs using the HTTPS protocol instead
  of HTTP. This might break existing applications that rely on the exact URL
  structure being returned, hence this flag is disabled by default.
  NOTE: DISCID_USE_HTTPS will become the default in a future release. Please
  update your software to not rely on the exact URL structure being returned.
