This subclass adds support for a block-based action on UIMenuItem.
If you are as annoyed about the missing target/action pattern, you will love this.
If you use PSMenuItem with the classic initWithTitle:selector initializer,
this will work and be handled just like a UIMenuItem.

Installs the menu handler. Needs to be called once per class.
(A good place is the +load method)
Following methods will be swizzled:
- canBecomeFirstResponder (if object doesn't already return YES)
- canPerformAction:withSender:
- methodSignatureForSelector:
- forwardInvocation:
The original implementation will be called if the PSMenuItem selector is not detected.
@parm object can be an instance or a class.
