fix a bug related to semantic predicates in the lexer and generally cleaned up variable and method names in the simulator. I moved all of the predicates to the right side of lexer rules in the unit tests. Later, we should ensure that predicates only occur on the right edge of lexer rules. We should state that the rule is not been accepted so we can't test things like getText(), we have to use more raw indexes into the character stream. In the lexer simulator, the addDFAState() method now does not try to compute whether there is a predicate in the configurations. That information has already been set into the ATNConfigSet by the getEpsilonTarget() method. [I should also point out that I have not tested the Java parsing in a while and now it hits a landmine on a number of common Java files in jdk :(. I'm not sure where that crept in]

added listener unit tests. fixed bug that didn't create ctx getters properly for recursive rules. added Symbol extends Token to parse tree stuff. added visitTerminal to Visitor. recursive alts now track their original, unedited AltAST subtree so we can properly count rule refs etc... later. dup of RuleRefAST was making wrong node. don't gen dispatch methods if no listener.
