[antlr-interest] Build errors for ANTLR 3.13

I ran into this, too. The build.xml file is erroneous in some way. It  
generates the parsers used by ANTLR in (I think) ./generated, and  
includes that on the build path. But at the same time, these classes  
already come checked in with the source in ./src.

I fixed this by manually copying the generated java sources  
and .tokens files from ./generated to ./src and removing ./generated  
from build.path in build.xml.

It would be nice though to have a working build file. I have no idea  
why the generated files are checked in and included in ./src, I think  
this is rather bad practice.

Martin
