[Yaroslav Chvanov]

From: Yaroslav Chvanov <[e-mail]>

In IPropertyPageSite implementation of OleCreatePropertyFrame handle
PROPPAGESTATUS_DIRTY notifications in OnStatusChange method by sending
PSM_CHANGED to the dialog window.

Tested with LAV Filters' LAV {Audio,Splitter,Video} configuration
windows, changing any options now makes the 'Apply' button active.
