SetLastError in CreateWindowEx

[Dan Hipschman]

I noticed that sometimes when CreateWindowEx fails and the app tries to
display a helpful error message, you get something like "Couldn't create
window: Success."  These are the error codes that XP sets for the given
failures.

ChangeLog:
* Correctly call SetLastError in a few places where CreateWindowEx fails.
