Win32 testing request

[Dirk Hohndel]

So I spent much of today completely redoing the way I create Windows
installers. I believe I have a working Qt5 based (!) Win32 installer and
would appreciate if a few people could give this a test, both on Win32 and
Win64.

>From my brief testing it appears to give an odd warning at start when
running on a 32bit Windows (it basically appears to always think it's
running on a 64bit Windows and "warns" about that, even if you are in fact
on 32bit Windows), but other than that I hope that it works :-)

If this works well we might even consider going back to just one Windows
binary... now that Qt5 works on 32bit there isn't really much of a reason
to do a dedicated 64bit binary. Or am I missing something? Hmm... I seem
to think there was something with time_t that was odd, but I think we
fixed that, right?

Anyway, please give it a try

Thanks
