EduGain Metadata integration

[Alan Buxey]

okay, so the older 0.8.0 version only worked with openjdk 1.7 (wouldnt
work with openjdk 1.8.0 or Sun Java 8 - due to the Spring changes)

the newer 0.9.2 wont work with this stuff because the config/mda.xml
some (lots of?) changes to align with the API adds/removes/changes -
this file is in the "eduGAIN-Metadata-Processing.zip" archive that you
download - thus that file needs a refresh.  I've never seen that file
before
yesterday and have done some quick updates.... changing eg
java.io.File to the springframework.  the older errors are now gone,
am now just
dealing with
