[fluxus] guile 1.8

[Dave Griffiths]

finished the guile 1.8 update, everything should be working again.

I've also updated the scripts for the new every-frame syntax. All the
scripts seem to work ok.

I had a bit of a fight with guile over vectors, in order to produce
vectors that we can use with ordinary functions - ie vector-ref, rather
than f32vector-ref, I have to build them in quite a slow way (element by
element rather than just giving it a block of data).

not sure what the best approach is here, I would have thought you wouldn't
have to worry about the type so much in Scheme code... maybe it's worth
the speedup of using functions like f32vector-ref - maybe I need to read
more docs...

cheers,
