Annotator v2.0.0-alpha.3

Features

• The authz, identity, and notification modules are now
  exposed as public API on the annotator page global.
• The notifier, identityPolicy and authorizationPolicy are now
  retrieved from component registry. It should now be possible to register
  alternative implementations.
• Performance of the highlighter should be slightly improved.
• Showing the viewer with a mouse hover should be much faster when there are
  many overlapping highlights. (#520)
• The getGlobal() function of the util module has been removed and
  Annotator should now work with Content Security Policy rules that prevent
  eval of code.
• The markdown extension has been upgraded to require and support version
  1.0 or greater of the Showdown library.

Bug Fixes

• Fix a bug in the ui.filter extension so that the filters option
  now works as specified.
• Make the highlighter work even when the global document symbol is not
  window.document.
• Fix an issue with the editor where adding custom fields could result in
  fields appearing more than once. (#533)
• With the autoViewHighlights options of the viewer, don't show the
  viewer while the primary mouse button is pressed. Before, this prevention
  applied to every button except the primary button, which was not the intended
  behavior.

Documentation

• Fix some broken links.
• Fix some example syntax.
• Add example markup in the documentation for the document extension.
