Fixed precedence bug in reading infix operators up against open parens.

Fixed divreg instruction for when operands are expressions.

added:
option/3,
numbervars/1,
random/3,
numlist/3,
sum_list/2

the main changes: biassert.c/token_xsb.c - got rid of the warnings
the others are just recompiled dlls.

Also, basics.xwam & xsb_read.xwam got recompiled - probably somebody forgot to commit.
