Initial support for IE View->Privacy. To support this menu option the active document now implements

the Exec command for the CGID_ShellDocView group and command id 75. We invoke the DoPrivacyDlg function
exported by shdocvw and pass in our implementation of the IEnumPrivacyServices interface. 

The actual privacy data is gathered and maintained by the UrlmonUrlRequestManager. If we detect a privacy
violation we notify the shell browser via the ITridentService2::FirePrivacyImpactedStateChange function
which ensures that IE displays the privacy icon.

Thanks to stoyan for his help in getting this done.

I will add tests in a followup CL.
