/** @short internal helper to bind e.g. MAC-Menu events to our internal dispatch API.
@descr On e.g. MAC platform system menus are merged together with some fix entries as
e.g. "Pereferences" or "About". These menu entries trigger hard coded commands.
Here we map these commands to the right URLs and dispatch them.
This helper knows a frame and it's container window (where VCL provide the hard coded
commands). We hold those objects weak ... so there is no need to react for complex dispose/ing()
scenarios. On the other side VCL does not hold us alive (because it doesn't know our UNO reference).
So we register us at the XWindow as event listener also to be sure to live as long the XWindow/VCLWindow lives.
