Accessing main window menus during C++ test run

Hello Xisco, thanks for your message.

Unfortunately this blog post, while instructive, is not really helpful 
as the accessibility approach is mentioned as having been discarded 
mostly because the accessibility implementation in LO was deemed not 
robust enough, so not a reliable basis for designing a new framework on top.

Unfortunately here I'm actually *trying* to exercise the accessibility 
implementation in the hope it'll help with improving it, so I cannot 
just ignore it :)

Thanks anyway, and any more knowledge would still be highly appreciated!
