OpenSAML renaming

In order to make this library and its OpenSAML 1.0.1 dependency co-exist in GT4 with the OpenSAML 0.8/patched, we modified the package location from org.opensaml to org.opensaml.v1_0_1. We renamed the classes, changed the name of a configuration file and the location of the schemas and rebuild the library. We also forced 1.4 compilation to allow to run on Java 1.4.x.

This file contains all the modification we had made.
