Update of parts/javasupport to antlr-2.7.2

[Oliver Kellogg]

Hi,

I don't use the Java support alot, but I find that
the class view is empty. (I.e. there is only the
"Classes" folder displayed, but nothing inside.)

Was it always like that?
Perhaps my update to ANTLR 2.7.2 broke it <ugh> ?

P.S.
I found that the new ANTLR always wants an AST factory
associated with the parser object, see parts/javasupport/
backgroundparser.cpp revision 1.7. Maybe there are more
differences that I'm not yet aware of...
