tldr — self-destruction and bug fixes 💣

Changes

• It's now possible to destroy/uninitialize a reveal.js presentation. This will remove all event listeners and roll back all changes made to the DOM. It will also unregister all plugins and destroy them if they expose a destroy method. (#1145 / @hakimel)

  Reveal.destroy();

• You can now provide an absolute URL to the presentation that should be loaded in the speaker view. This is useful if you have a presentation integrated as part of a web page but still want the speaker view to work.

  Reveal.initialize({ url: 'https://example.com/my-reveal-presentation' })

• Source maps are now included in dist (#3082 / @dabrahams)

Fixes

• Fix the speaker view no longer goes out of sync with your presentation after live-reloading (#2822 / @hakimel).
• Fix XSS vulnerability in speaker view (#3137 / @r0hanSH)
• Fix issues with scaling embedded presentations when entering fullscreen mode in Safari (#3080 / @Martinomagnifico)
