Allow to configure whether to create a snapshot during content package installation

It would be nice to be able to somehow influence whether a snapshot should be created prior to installing the content package (using JcrPackage.extract(...), http://jackrabbit.apache.org/filevault/apidocs/org/apache/jackrabbit/vault/packaging/JcrPackage.html#extract(org.apache.jackrabbit.vault.fs.io.ImportOptions)) vs. JcrPackage.import(...)).
