patch for the missing lib/ stuff.
I guess i think its bogus that lucene/tools depends on jars in lucene/test-framework without even calling 'resolve' first. I think it should just depend on ant itself for now? this is how the other modules are done.
its also confusing lucene/test-framework doesnt just depend on its own lib/ but instead junit-path + ant-path (which add up to that, but i dont like it). These paths are separately needed for e.g. running tests and other things, but shouldnt be used here.
