[antlr-interest] Simple Antlr3 grammar not working in AntlrWorks 1.0b9

[Terence Parr]

Fixed this bug.  Added unit test.  New antlr build.

http://www.antlr.org:8888/browse/ANTLR-96

Build: antlr-03-26-2007.18.tar.gz

fixes:

* CommonTreeNodeStream didn't push correctly; couldn't handle very
   deeply nested trees.

* Fixed bug that E : 'a' 'b' ; made E be seen as an alias of 'a'.
