commctl32 datetime styles synchronization fix

[Siim Karus]

As I was testing with OSE (binary: http://www.ut.ee/~siim04/OSE/OSE.exe , 
source: http://www.ut.ee/~siim04/OSE/OSE.cpp), I found that style information 
returned by GetWindowLongPtr differs from what is stored in DATETIME_INFO 
structure (infoPtr). I added some synchronizational lines (a call to 
SetWindowLongPtr and a copy from window create structure). There seems to be 
some strange problem with setting DTS_SHORTDATEFORMAT flag never reaches 
DATETIME_StyleChanged . It seems the flag is being cancelled before it ever 
reaches DATETIME control :(.
