[antlr-interest] Lean runtime jar

[Joan Pujol]

If you use IDEs like JBuilder you can configure to generate an
outputjar optimitzed removing the classes that are not used.
Also you can use tools like Proguard that's an ofuscator/optimizer
that does this job.
But you have to be careful because ANTLR use reflection in some
places, and that tools don't manage well reflection.
