The slow controls SDF IOCs have been updated to a newer release.  It is running RCG from trunk at revision 4114.

The SDF IOCs are configured to load straight to the OBSERVE.snap file (skipping the safe.snap which we do not use).

Changes:

• Autodetection of channel types (eases sysadmin workload).
• Fixed a bug with revert that was discovered last power outage.
• Better precission in the saved snap files.
• Configured to load OBSERVE.snap.

With the precision changes I have accepted all numeric differences smaller than 10^-16.   These should not need to be accepted again until there is an actual change.
