[Muine] Multimedia support

[Lee Willis <lee leewillis co uk>]

Jorn,

    Revised patch at:

http://www.leewillis.co.uk/muine/mmkeys_4.patch

This should fix all of your points apart from the "Refresh" issue. This
really needs support in control-center which will have to wait until
Gnome 2.7. You can take out the refresh handling till then if you want
(I'll just maintain it locally :p)

Thanks
Lee
