ids theme: speaker notes overlay button for touch devices
The reveal.js speaker view ('s') opens a separate window, which is
awkward on mobile browsers. Add a button next to the fullscreen toggle
(shown on coarse-pointer devices only, like the fullscreen button) that
covers the slide with a full-screen overlay showing the current slide's
speaker notes, its title and planned time (from data-timing). The
overlay follows slide changes while open, closes with the X button or
Escape, is hidden in print output, and the button only appears when the
deck contains notes at all.

- `'s'` enable presentation mode with speaker notes when the Notes plugin is activated
+On mobile browsers (touch devices), a speech-bubble button next to the fullscreen button overlays the current slide with its speaker notes -- useful for practicing a talk on a phone or tablet, where the separate speaker view window of the `'s'` shortcut is awkward. The overlay shows the slide title, its planned time (if annotated with a timing comment), and the notes, and follows along as you change slides. It appears only if the deck contains notes at all.

Pressing `Esc` exits all of these modes.
