/***********************************************************************\
FUNCTION: _DoOptions
DESCRIPTION:
The user selected either "Folder Options" or "Internet Options" from
the View or Tools menu (or where ever it lives this week). The logic
in this function is a little strange because sometimes the caller doesn't
tell us which we need to display in the pvar. If not, we need to calculate
what to use.
1. If it's a URL pidl (HTTP, GOPHER, etc) then we assume it's the
"Internet Options" dialog. We then use psv->AddPropertySheetPages()
to create the "Internet Options" property sheets.
2. If it's in the shell (or FTP because it needs folder options), then
we assume it's "Folder Options" the user selected. In that case,
we get the property sheets using _pbsOuter->CreateBrowserPropSheetExt().
Now it gets weird. The PMs want FTP to have both "Internet Options" and
"Folder Options". If the pvar param is NULL, assume it's "Folder Options".
If it was "Internet Options" in the internet case, then I will pass an
pvar forcing Internet Options.
NOTE: SBO_NOBROWSERPAGES means "Folder Options". I'm guessing browser refers
to the original explorer browser.
