IDX iocs all updated to idx v1-4
To accommodate a request by the SME, each of the IDX iocs have been updated to a new version v1-4 of the idx controls. This restores a PV that indicates when a detector is reaching or exceeded saturation. Each of the iocs have been successfully rebooted and restored. Screen updates and clean up also done.

BSList #117047: quick comparison with pre-activation run
Got some unscheduled beam time and used the opportunity to check if the absence of IHA0I02 background due to A2 being retracted changes the outcome of a lens scan at all.
Figure 1: MFX1I03 = 198, VWien = 90 deg
Figure 2: MFX1I03 = 198, VWien = 0 deg
Behavior similar to before (#4466680, note figure order is reversed) but not identical. Unfortunately, the photocathode got reactivated in the meantime, so it may just be the beam shape being different.
We will use this result as a reference for Friday's data-taking run.

HarpFitter: IHA0I02
Comments:
With A2 fully retracted, the background observed previously is gone. Also, this harp has its original name back now that Tony has swapped the harp chassis.
