Add an helper to initialize downloads.

2003-10-24  Marco Pesenti Gritti  <marco@gnome.org>

        * embed/mozilla/MozDownload.cpp:
        * embed/mozilla/MozDownload.h:

        Add an helper to initialize downloads.

        * embed/ephy-embed-persist.h:

        Add a flag to ask destination.

        * embed/mozilla/EphyHeaderSniffer.cpp:
        * embed/mozilla/EphyHeaderSniffer.h:

        Use the helper. Add code to determine a good
        filename.

        * embed/mozilla/mozilla-embed-persist.cpp:

        Use a MozDownload directly if there is a dest set,
        it doesnt make sense to use sniffer for favicons.
