WyCS: fixed bug with the wycs debug mode
WyRL: added support for manual rule ranks.
Now you can specify a numeric rank for your rewrite rules which are then sorted accordingly.  This should hopefully allow me to optimise certain cases more aggressively.
I have also manually ranked the rules in the Solver, although this has not had any significant effect on performance.  Instead, I believe that some empirical data examining different orderings would help.  #387
