[wix-users] Avoid Bundle Resume After Reboot

[Edwin Castro]

Thanks Blair!

I'm going to educate myself in WM_QUERYENDSESSION. Based on messages I've
seen in bundle logs I guess that burn might handle WM_QUERYENDSESSION
itself too. Is that a correct guess?

This still will not protect us against automatic resume after a system
crash but perhaps we can limit automatic resume to just system crashes.
