Added Schematron QuickFix library

Added first draft of Schematron QuickFix library for library.sch
Extended library.sch and rules.sch for the QuickFix library
The changes are designed in a way, that it is still possible to use the library.sch without Schematron QuickFix support.
To activate the QuickFix support, it is necessary to include the the quickFix-library.xml into main Schematron schema (example rules.sch).
