Balthisar Tidy 3.7.0

• Balthisar Tidy and Balthisar Tidy for Work:
  • Update to HTML Tidy 5.7.0.
  • New Tidy options such as add-meta-charset, priority-attributes,
    show-meta-change, keep-tabs.
  • You can now double-click into a Tidy Option with a text field, and the text
    field will activate.
  • You can triple click a text field that uses lists, and the list editor will
    pop up. This can be much nicer than managing long lists in a single string.
  • Tidy Option text fields that are lists now reflect the proper formatting for
    lists.
  • Adopted all of the new Tidy Option categories offered by the latest HTML
    Tidy.
  • We now issue advice to turn on force-output if a loaded document produced
    no content.
  • Removed the markup Tidy option, because Balthisar Tidy handles this
    automatically.
  • Updated the Help book to include updates to Tidy options.
• Developer changes:
  • Internal changes to make future maintenance of Balthisar Tidy better.
  • I've removed all of the different, redundant targets, and now different
    versions are built via the xcconfig files.
  • Built versions of Balthisar Tidy are now a smaller. The Tidy Extensions
    and Tidy Service Helper now rely on Balthisar Tidy's frameworks where
    possible rather than including their own, duplicate copies.
