XNAT-4482 Removed old Saxon dependencies, which used a configuration

file format that became unsupported as of Java 8. Replaced with last
open release of primary Saxon 9.1.0.8 library (newer Saxon-HE library
changed API so that PipelineManager didn't compile, and other XPath
implementations would also require migrating that same code).
