Setting up flyout formatting as a separate formatting option

This is replacing the implementation I did for 'html-light'.
The reason html-light doesn't work is that we don't have any way
of reliably determining which parameter should be the one that is
linked to in the notification title (flyout notifications are only
supposed to have one link). With this system, the notification
definer can specify a separate message/params combination to use
specifically for the notification flyout. If they don't specify
these, it falls back to the normal title message/params.
