v0.2.0-rc.1

• 🚀 NEW: The key-control attribute
  accepts values of none or escape,
  to turn off keyboard navigation
  (and optionally leave escape-to-blur intact).
  This attribute can be applied to individual elements in a deck,
  for more detailed control --
  eg turning off navigation while a form has focus.
• 🚀 NEW: Provide a slide-deck.webc component.
• 🚀 NEW: All attributes have associated getters and setters:
  • key-control -> keyControl (boolean | 'none' | 'escape')
  • follow-active -> followActive (boolean)
  • full-screen -> fullScreen (boolean)
  • slide-view -> slideView (string)
• 🚀 NEW: Use the ?slide-view=viewName query parameter
  to create links to specific slide views.
  When present on load, the query parameter will override
  the session storage as well as any hardcoded attribute value.
• 💥 BREAKING: The slideView property setter
  should be used for changing views,
  rather than manipulating the slide-view attribute directly.
  This will also update session storage and the url query parameter.
• 💥 BREAKING: When the start and resume events are fired,
  the slide-deck is put into a publicView
  (the default is slideshow).
  When the join-as-speaker event is fired,
  the slide-deck is put into a privateView
  (the default is speaker).
  These can be changed by setting the
  publicView and privateView properties with JS,
  or by setting the public-view and private-view attributes in HTML.
• 💥 BREAKING: Renamed the custom event handlers and matching public methods:
  • reset = reset()
  • join = join()
  • resume = resume()
  • start = start()
  • join-as-speaker = joinAsSpeaker()
  • blank-slide = blankSlide()
  • next = next()
  • previous = previous()
  • to-slide = toSlide()
  • to-saved = toSavedSlide()
  • scroll-to-active = scrollToActive()
  • full-screen = toggleFullScreen()
  • key-control = toggleKeyControl()
  • follow-active = toggleFollowActive()
• 🐞 FIXED: Keyboard events are given proper priority, so that
  (for example) you can open the control panel from a blank slide
• 👀 INTERNAL: Renamed static storageKeys to storeValues,
  and static controlKeys to navKeys for clarity.
