this is a change in behaviour, but i think it makes sense. before we skipped things like the jcr:resource of an nt:file node, which is stupid and confusing. the intention was to not dump the version history and similar things by default, and to not delete that in the purge operation.

@dantleech so now this would be the place for your input as i closed #73 and merged into here to avoid the testing chaos i produced. ok if we do that?
