[antlr-interest] ANTLRWorks debugger output

Currently AntlrWorks does not echo output from debugged grammars to the
console, and it doesn't appear on the launching console (if any) either.
Thus errors that aren't displayed in the parse\debug tree are not reported
to the user at all. For instance an exception in an action can cause the
debugger to silently terminate the grammar. Also, with larger debug input it
is often hard to see errors in the parse tree. If they were also printed to
the console (or a seperate grammar output console) it would be easy to see
if there were any grammar probvlems. Highlighting them in the parse tree
would also be nice but console output would be better for quick regression
checking.
