NCM-YAIM and ORACLE_LOCATION

It turns out that many of the non service specific values in a YAIM site-info.def file are hard coded into the NCM-YAIM component. There are I guess some good reasons for doing this but it makes adding a new one quite a painful process. Anyway a good opportunity to try and update and release a YAIM component to CERN. Luckily as always there are ways around it and I can continue with the test installs. All five nodes installing now hoping for working system this time....
