Changed paths in default recipe for kibana source to the new kibana directory structure...

This may be a breaking change to people using older branches/commit sha1's of kibana.    I branched off `kibana3-before-es-builds` before pulling this merge to make it easier for them to find what they're looking for.   Given that kibana3 itself is making 'sort-of' breaking changes by only offering kibana-latest build via the official build download,  I think it's okay if we do the same here, as long as we're not assholes about it.
