        <rdar://problem/5270958> REGRESSION: Complex system KeyBindings don't work properly

WebCore:
        * dom/KeyboardEvent.h:
        (WebCore::KeypressCommand::KeypressCommand):
        (WebCore::KeyboardEvent::keypressCommands):
        Change stored command class to preserve complete information about commands.

        * editing/EditorCommand.cpp: (WebCore::CommandEntry::): Mark InsertText as a text insertion
        command, which it is. Previously, we couldn't do it because WebKit didn't really treat insertText:
        as a command.

        * page/EventHandler.cpp: (WebCore::EventHandler::keyEvent): Copy commands saved while interpreting
        a keydown event into keypress, to avoid losing state when running interpretKeyEvents: again.

WebKit:
        * WebView/WebHTMLView.mm:
        (-[WebHTMLView _interceptEditingKeyEvent:shouldSaveCommand:]): Made command replaying work
        when handling keypress, too.
        (-[WebHTMLView doCommandBySelector:]): Adapted for the new way to store commands in events.
        (-[WebHTMLView insertText:]): Append a command, not replace the whole existing vector. Also,
        restore the state for additional commands to be saved correctly.
