Removed adding indexes via GenericSetup XML file, since they are already being added in
the setuphandlers.py of PAM.
Since the indexes are already added in plone.app.multilingual, we can handle adding the metadata for the catalog there too
Added a separate testing profile for Generic Setup. Catalog indexes are still
being added via xml, but only for testing. This extra profile does not appear
in the portal_setup tool.
Merge pull request #4 from pysailor/master

Don't add indexes via xml to prevent purging on reinstall
