WineMine cannot save score on Windows

[Pavel Roskin <proski@gnu.org>]

Hello!

It's a resend.  Hopefully I'll try to explain this patch better this time.
WineMine calls RegCreateKeyEx with uninitialized SECURITY_ATTRIBUTES
argument.  Wine accepts is, but Windows 2000 doesn't.  As a result,
Winemine fails to save score on Windows 2000.

Also, WineMine passes the "disp" (disposition) argument but doesn't use
it.  Those arguments have been replaced with NULL.

ChangeLog:
	* programs/winemine/main.c:
	Don't pass unused pointers to RegCreateKeyEx() - this
	prevents score saving on Windows 2000.
