[Reviewer: Andy] SAS parameter compression

Andy,

Please can you review my changes to the SAS resource bundle to enable parameter compression?

We haven't live-tested this yet - waiting for your changes.

The quotes here are unnecessary and, in fact, the YAML exporter in Ruby (which would be used when a user asks to export a resource bundle) does not put quotes in unless it has to (escape characters).  I only mention this as it means import then export is not the identity.
