Beginning fix for KeyEvent,KeyboardEvent and UIEvent changes in roll 45

tools/dom/src/dart2js_KeyEvent.dart

 /**
  * A custom KeyboardEvent that attempts to eliminate cross-browser
  * inconsistencies, and also provide both keyCode and charCode information
  * for all key events (when such information can be determined).
  *
  * KeyEvent tries to provide a higher level, more polished keyboard event
  * information on top of the "raw" [KeyboardEvent].
  *
  * The mechanics of using KeyEvents is a little different from the underlying
  * [KeyboardEvent]. To use KeyEvents, you need to create a stream and then add
