Cornerstone build.xml

[Daniel Krieg]

I just pulled Cornerstone from CVS and the build.xml generatemeta target is
still doing a taskdef where classname=
"org.apache.avalon.phoenix.tools.metagenerate.MetaGenerateTask" rather
that "org.apache.avalon.phoenix.tools.metagenerate.MetaGenerateQdoxTask"
thus causing the main build target to fail.
