Select some HTML content on a password-protected webpage that has
images, copy, paste into Writer when it's in LOK mode -> hang.
What seems to happen is that the HTML content itself is on the
clipboard, but not resources referred by that content, like images.
Which means our code in SwHTMLParser::InsertImage() will at the end call
into ucb/ code to get the HTTP image, which will call into uui/ code to
ask for the password. This has multiple problems: 1) the popup dialog is
not async (and not trivial to convert to async) and the dialog hints
that the password can be saved, but LOK document edit sessions always
start from a clean profile, so that's not working. The non-async dialog
even results in a hang in practice.
Fix the problem by not showing the password dialog in the LOK case at
all: it's better to have an image placeholder in the paste result than
hanging your entire document edit session.
Non-password-protected images continue to work, unless
HostFilter::isForbidden() rejects the URL.
