Prevent display sleep and enable wake lock in all Android and iOS web browsers.

This fork merges many of the community fixes/features into a single place. The following sources were used:

Doxee/NoSleep.js - iOS and Samsung browser fixes MaRossetti/NoSleep.js - feature to specify a title CorentinChauvin/NoSleep.js - fix autoplay DOMException by muting the audio suxscribe/NoSleep.js - fix for Opera in Android

Create a new NoSleep object and then enable or disable it when needed.

To create a new NoSleep object:

var noSleep = new NoSleep("Optional Title");

To enable wake lock:

NOTE: This function call must be wrapped in a user input event handler e.g. a mouse or touch handler

// Enable wake lock.
// (must be wrapped in a user input event handler e.g. a mouse or touch handler)
document.addEventListener('click', function enableNoSleep() {
  document.removeEventListener('click', enableNoSleep, false);
  noSleep.enable();
}, false);

To disable wake lock:

// Disable wake lock at some point in the future.
// (does not need to be wrapped in any user input event handler)
noSleep.disable();
