[Fluxus] couple of editor fixes

[Kassen]

Evan;

This might not be that hard. We already need a function that takes a string
(which represents the contents of the buffer) and maps that to a way of
displaying these characters. We already have that in Fluxus and so does that
proof of concept that I did (these just create a new line at every [enter]
and set a scale but still). The one thing we'd need for your plan here is a
way to replace that function by a new one, which seems very much in tune
with the rest of Racket where you can do similar things with error handlers
and the like. The relevant function would have to be called every time the
text changes (and perhaps also when we manually do so, for example to have
it all react to music). This sounds quite realistic to me. It also sounds
like the kind of thing that will lead to large amounts of foot-shooting but
so far we have been very supportive of that already. This would also lead to
user-definable syntax highlighting and so on. To me this makes sense.

Yours,
Kas.
