Fix .mailcap html/calendar/etc. attachment viewing

Using 'needsterminal' forces mutt to wait before deleting the
attachment from a temp folder. By default this is something like
3 seconds, which is less time than it takes (at least on my old
macbook pro) to open a new firefox tab or get ical to respond.
'needsterminal' forces mutt to hang until you've confirmed the
file is open by hitting 'enter', and I believe it doesn't
delete the file until that time.
