annotator 2.0.0-alpha.3 on Node.js NPM

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.

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.
