Improved Generator for testing sets of results 0.02

For completeness, here is an improved standalone test of the Wichmann-Hill
32-bit pseudo-random generator from 2005-2006.

Because it is standalone, instead of customized for Calc, there is an
snewrandom() function for specifying a seed.  Although a random source can be
used, this will also provide good separation even with regular seeds
(1,2,3,...) or using something with low entropy such as too-recent repetitions
of time(NULL).

I also made adjustments to stay within ISO/IEC C 1995.  There should be no
platform dependencies so long as the long type has at least 4 bytes.

This may be useful in comparisons as well as testing the basic WH PRG.
