Add physcalc (unversioned), an extremely old (apparently first written

in 1990), but still quite useful and flexible calculator.  Basically it's
units(1) on steroids.  Also added patches to make physcalc secure (who
knows, someone might make a cgi interface to it); also allowed it to
actually read its *.phy files in another directory.

+Physcalc is a neat mathematical calculator that does conversions
+from many different units in many forms, and is extremely flexible
+as far as specifying math problems go.  You can also add your own
+types of conversions.
