[antlr-interest] Change in output location with 3.0b7

[Martin Fowler]

I've just upgraded to 3.0b7 and I noticed a change in where Antlr puts 
its output files (didn't spot it in the update log.)

Previously if you specified an output directory with -o and you had a 
grammar in a subdirectory it would put the output in the corresponding 
subdirectory in the output directory. Now it just puts it directly in 
the subdirectory. I'm not saying this is wrong, but I thought I'd point 
it out as it's caused my stuff to break :-(

I've been intending to write a little program to walk my src directory 
and use the API to generate output files if necessary in a corresponding 
gen directory (which I can keep out of version control). (I have a lot 
of them as I'm exploring lots of alternative langauges and parsers 
within the same project). If nothing else I guess this makes me want to 
do it. But if there's an easier way to do this or someone's already done 
it do let me know ;-)
