A matching pre-release for parsedown@v2.0.0-beta-1

This is a pre-release.

There are a few bugfixes, mostly changes have been towards compatibility with the latest Parsedown beta.

0.7.1 was released a while ago under the 0.7.1 tag, but GitHub release notes weren't added: causing https://github.com/erusev/parsedown-extra/releases/latest to link to version 0.7.0 as the latest release. These release notes only fill the purpose of updating that link and the latest release as noted by GitHub.

• block level elements inside definition list descriptions;
• better names of util methods;
• fixes (#40);
