Update SciFi parameters in master + XML bugfix
This will update the master to include more SciFi alignables, and also adds the functionality to output the SciFi alignment constants in xml (relative to v17r0)
The new SciFi alignment scripts also have associated tests within Escher.
EDIT: xml output bug present in master is fixed in this branch, test align-ft-modules now passes.
