* 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: () => { ... } }`
Commit 3729976 only updated xgettext.html which generates the .pot file.
This commit also makes sure that the actual translations are applied to
the interface.
