Bug fix for the model-free results.write() problem.

This bug was reported by Gary Thompson at
https://mail.gna.org/public/relax-devel/2007-03/msg00176.html (Message-id:
<460CE499.9070905@...>). The thread continues into the next month
(https://mail.gna.org/public/relax-devel/) starting at
https://mail.gna.org/public/relax-devel/2007-04/msg00028.html (Message-id:
<460CE499.9070905@...>).

The fix was to synchronise the relaxation data assembly in the value and simulation sections of the
write_columnar_results() function. The 'num_ri' test was missing from the simulation section!

Major update - monte carlo simulations supported (trivially)
also implimented: chunky queues, exception throwing on slaves, and rank
annotated output. note uniprocessor support currently broken.
