* Fixes to the Keyboard Handler to make it work better --

* drop keypress event (not used, registers as keydown in IE< which results
      in double events) 
    * return evt instead of evt.keyCode || evt.charCode, so apps can do
      whatever they like best
 * adjust ModifyFeature to new API
 * Adjust KeyboardDefaults to new API, and include a new set of keyCodes
    in switch statement to catch more cases
 * Include keyboard defaults test in list-tests.

Patch from tcoulter, work from Pedro Simonetti (See #1108), Paul Spencer,
myself. r=pagameba,me (Closes #1292)
