[antlr-interest] assign a derived token to the lexer

[thomaskrebs]

I want to assign a different Token than CommonToken to the lexer. In 
lexer.html at lexer.html#Token_Attributes it is documented how to do 
that. But this seems to be wrong:

ImageToken t = new ImageToken(IMAGE,$getText);

t.setAttributes(attrs);

$setToken(t);

I assume t should be a pointer to ImageToken and the parameter to 
setToken can not be a Token or a pointer to a Token but a RefToken. 
But I cannot assign a RefCount<ADerivedToken> to the _token inside 
the parser rule. How to deal with that?
