[antlr-interest] token name from token type

[Ron Hunter-Duvar]

I ran into the same problem. I may be wrong, but it seemed like 
functionality that was intended to be implemented in Antlr but was never 
finished, at least in the Java run-time. I just hacked together a method 
that uses introspection to pick out all the token type declarations 
("public static final int XXX = nnn") at startup and put them in a hash 
table. There might be a better way to do it, but this was easy enough 
and got the job done.
