[Fluxus] commit: seperated install

[Dave Griffiths]

Hi all,

So, the fluxus collects (the scheme code and plt extension binaries) now
install to prefix/lib rather than into plt scheme's collects path.

The collects paths for plt and fluxus are passed into the interpreter
and are accessible via plt-collects-location and
fluxus-collects-location.

I tested this by installing fluxus to a 'test' dir in my home directory
as a normal user, deleting the centrally installed one, so you get:

~/test/bin/
    fluxus-0.16
    fluxa-0.16
~/test/lib/fluxus-0.16
    ...scheme code & compiled extensions...
~/test/share/fluxus-0.16
    ...meshes,shaders,textures and fonts...


So everything can be put in one place, which seems much more packagable.

cheers,

dave
