Use of the sequence "FDUP F*" is ubiquitous in Forth scientific code for
lack of a common word which squares an fp number. This not only is less
readable but does not convey as much meaning to anyone who is reading
the code.

I've updated the FSL modules in kForth (32, Win32, and 64) to remove use
all instances of "FDUP F*" with the (built-in) word FSQUARE. Some FSL
modules provided definitions of FSQR for the same function (by MHX) and
I replaced these instances with FSQUARE which I find more readable and
less error-prone due to the proximity of FSQR to FSQRT.
