Override short-cuts to common editor commands

To ensure Chromium is given a chance to handle editor commands,
we must override these short-cuts.

On OS X we must also perform the action afterwards as these are not
handled internally by the Blink Editor.

The patch solves copy/paste in flash plugins and copy/paste on OS X
when no application short-cuts have been defined. The handling of
short-cut override events is based on how it was handled in Qt WebKit
