[fluxus] scheme debugging commit

[Dave Griffiths]

Hi all,

I've finally got proper debugging working inside fluxus. First news is
that the debugger is on by default now - it used to be off, which means
that the interpreter will run slower now, use (debug-disable 'debug) to
get the speed back.

The way to control debugging is a bit hard to get info on, but is mainly
through this interface:

http://www.gnu.org/software/guile/docs/docs-1.8/guile-ref/Debugger-options.html#Debugger-options

the most useful by far is:
(debug-enable 'stacktrace)
to get, well stack traces

and also:
(read-enable 'positions)
to get the line numbers out (yep we need line number support now ;)

cheers,

dave
