Add scroll view

[hakimel]

Reader mode lets you turn any reveal.js presentation into a tall scrollable page with slides stacked on top of each other. If there are fragments, those will be triggered through scrolling as well.

Activate it by initializing reveal.js with view config value set to "reader".

Reveal.initialize({ view: 'reader' })

New config values added for the reader mode:

// Can be used to initialize reveal.js in one of the following views:
// - print:   Render the presentation so that it can be printed to PDF
// - reader:  Show the presentation as a tall scrollable page with scroll
//            triggered animations
view: null,

// Adjusts the height of each slide in reader mode
// - full:       Each slide is as tall as the viewport
// - compact:    Slides are as small as possible, allowing multiple slides
//               to be visible in parallel on tall devices
readerLayout: 'full',

// Control how scroll snapping works in reader mode.
// - false:   	No snapping, scrolling is continuous
// - proximity:  Snap when close to a slide
// - mandatory:  Always snap to the closest slide
//
// Only applies to presentations in reader mode.
readerScrollSnap: 'mandatory',

// Enables and configure the reader mode scroll bar.
// - 'auto':    Show the scrollbar while scrolling, hide while idle
// - true:      Always show the scrollbar
// - false:     Never show the scrollbar
readerScrollbar: 'auto',

// Responsively activate the reader mode when we reach the specified
// width (in pixels)
readerActivationWidth: null,

The core functionality is in place but I'm going to try a few more ideas (like triggering auto-animations and add a vertical progress bar).
