Propsheet pages need WS_EX_CONTROLPARENT style

[Zach Gorman]

Propsheet pages need the WS_EX_CONTROLPARENT extended style set. 
Otherwise, WM_NEXTDLGCTL does not work properly when crossing from 
the property sheet into the property page. Also, this is required 
(along with a forthcoming patch) for default button handling in
property pages to work as expected.
