Replace crf files2
Long overdue branch to remove all template .crf files and replace with the equivalent .sbt files. This will allow users to load the templates (once again). Where necessary, this branch also adds -export.sbt files to preserve the export options, although export still wont work with cmb6 -- the export templates and python scripts must be retooled to use the smtk operator interface.
