* Prevent Cmd-Shift-M from minimizing on Mac EXCEPT on "Home" sub-screen
The problem is that hitting "Cmd-Shift-M" on mac always minimizes the app, even though it should only minimize on "Cmd-M", and not on "Cmd-Shift-M".
The code that minimizes (using the WXWidgets "Iconize()" call) happens in MainFrame.cpp keyboard event loop. The code that's checking, looks for "Cmd-M" but does not check for any other keyboard modifiers, so I added a check to ignore the event if Shift is pressed along with "Cmd-M".
There's a secondary issue that isn't really relevant to this bug in that the app will still minimize when pressing "Cmd-Shift-M", but ONLY on the "Home" sub-screen. (all other sub-screens work as they should).
I'm not sure why, but when the "Home" sub-screen is selected, the keyboard event loop (MainFrame.cpp, line 609), is called TWICE when "Cmd-Shift-<any key>" is pressed:
* Once where the event's wxKeyModifier (retrieved via `evt.GetModifiers()` is set to `wxMOD_CONTROL` AND `wxMOD_SHIFT`. (this is correct)
* Once where the event's wxKeyModifier is **ONLY** set to `wxMOD_CONTROL` (this is wrong).
Again, this double-event (with the wrong modifiers) only happens when the user is on the "Home" sub-screen. For the context of this bug the 3DConnexion preferences dialog isn't needed on the "Home" sub-screen so this secondary bug doesn't matter. But it does make the UX odd where Cmd-Shift-M will minimize the app when the user is viewing the "Home" sub-screen, but not minimize the app when the user is viewing any other sub-screen.
