Added "evaluatesToNumber" subroutine.  In conjunction with fix_answer_for_display filter, this now fixes a bug with displaying student_ans in a problem that allows strings for valid answers.

Changed NUM_CMP so that the calculated versions of the student's answer
and the professor's remain in the answer hash to be displayed by
displayMacros.

There are now slight clues, when using num_str_cmp that the
instructor's answer is a string. I'm not sure anyone can find them
easily.  Further refinements should be able to remove them in any case.

Simplified some of the scripts.  Using forking there is no need
to evaluate $main:: everytime, since it remains the same for both
the parent (where the script is compiled) and in the child where
the script is executed.

There were other minor fixes to work around bugs in 5.6.0 which were
fixed in 5.6.1
