Well, it had to get to the top of my to-do list eventually. I've been trying
to sort [1] the LADSPA website [2] LADSPA v1.1.

On the first point, I'm missing links to LCP and the XML GUI thing. Also, if
there are any plugins or hosts that should be on the list please shout (I
have added a few that people have told me about but I've not posted the new
index onto the web yet).

On the second point, here's a set of diffs for the new version of ladspa.h.
Do these look alright? I'd have preferred to put the default values in the
hint structure, but that would have changed its size and broken
backwards-compatibility.
