another minor translator enhancement

[Eric Dean Tribble <tribble>]

The translator currently handles most operators correctly.  Smalltalk
operators are almost the same as C++ operators.  Anytime it writes out
an operator name for a method, it prefixes it with 'operator'.  That
doesn't handle '[]' and '()'.  Did you change the parts of the
translator that currently do the 'operator' prefixing to use the new
routine?  I trust the standard override and selectorMap mechanism can
now handle all operators.
