I have updated the ODC EPICS settings for all SUS, ISI and HPI ODC channels.

I have also updated the safe.snap files containing these EPICS records, so that they are correctly set on reboots.  The attached files contain the list of changes made to the safe.snap files (nothing listed in the changes_*.txt file under the snap file name means no changes were made), and the modified files have been committed to the SVN.
