* Change copyright header
This updates the copyright header to say "The noVNC Authors". People
who previously had copyright listings are now under the AUTHORS file.
Always use the shorthand notation if the function is a method of an object or class `{ foo() { ... } }` or `class bar { foo() { ... } }`
unless it's a callback in which case you a fat arrow function should be used `{ cb: () => { ... } }`

where the browsers refuse to show the cursor. Handle both of these
cases by letting the browser render the cursor via a floating
canvas.
This allows us to support a local cursor at all times.
