user.exe16: Support Windows 1.x and 2.x Menus

[Martin Payne]

Hi Alexandre,

> Mainly I find it interesting that Windows 2 apps still work, it probably hasn't been tested in 20 years. Apart from the menu issue, are other things looking OK?

A few applications crash at startup with a null pointer dereference. I'd need to read up some more on Wine debugging to understand why. Icon and cursor resources don't load, but like with the menus it's just because the format is slightly different. It shouldn't be difficult to add support for that as most of the required code is already in Wine. Other than that, it's surprising how ~30 year old applications can still work on a modern OS!

Regards,
Martin
