Let's make TextInputHandler::HandleCommand() handle other commands which are caused by Backspace, Delete, Tab, ArrowUp, ArrowDown, ArrowRight, ArrowLeft, PageUp, PageDown, Home, End and Escape keys with various modifiers. This patch makes Korean users can do most key operation in editor even with composing Hangul character. Note that this patch has a hack for cancelOperation: command. The command is typically fired for Escape key press. However, it's also fired for Command + Period. Unfortunately, this behavior is really odd if subclass of NSResponder implements |void cancelOperation:(id)sender|. If it's implemented, Cocoa doesn't call its |void keyDown:(NSEvent)theEvent|. Instead, it calls only |void doCommandBySelector:(SEL)aSelector| and |void cancelOperation:(id)sender| when Command + Period is pressed. Therefore, we cannot dispatch keydown nor keypress event for this key combination if we implement it. Therefore, this patch doesn't implement the method but handle it in doCommandBySelector even though the super class of ChildView cannot handle the command with this path.
