Gnu Smalltalk 2.1.12:
  39 printStringRadix: 11  ===> 11r36

VisualWorks 7.3.1
  39 printStringRadix: 11 ===> 36

Squeak 3.7
  39 printStringRadix: 11 ===> 11r36

Squeak 3.8 and 3.9beta
  39 printStringRadix: 11 ===> 36

If we've moved permanently to the the VW-compatible version (no radix
prefix) then several classes in the base image need to be fixed (most
importantly for me UUID>>asString36 but there are others that assume the
radix prefix).  I'll post fixes to mantis unless some one pipes up with
"no we're going to go back to the old way."
