/** @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 its container window (where VCL provide the hard coded
|
|
commands). We hold those objects weak so there is no need to react for complex UNO dispose/ing()
|
|
scenarios. On the other side VCL does not hold us alive (because it doesn't know our UNO reference).

So we register at the VCL level as an event listener and
