Merge pull request #2671 from RosettaCommons/guffysl/deprecate_legacy_sewing
This branch deprecates the version of SEWING currently in master to legacy_sewing in preparation for the merge of the SEWING refactor. It also adds accurate xml schema for the legacy SEWING movers so that they can still be accessed through RosettaScripts. Integration test changes to continuous_sewing_hasher and discontinuous_sewing_hasher expected (namespace changes in tracers/options).
