WP13304 HEPI Pump controller upgrade.

Patrick, Erik, Jonathan, Dave:

Patrick's new H1EPICS_HEPIPUMPEX.ini was installed into the EDC and the DAQ was restarted.

As with previous upgrades, some old channels have new equivalents, so to preserve recent minute trend lookbacks these channels were copied to the new name before the trend writers were started.

Sequence for the restart was

11:33 Stop TW0 and TW1

11:34 Copy raw minute files on TW0 and TW1

11:35 Restart 0-leg 

11:36 Restart EDC

11:40 Restart 1-leg

11:41 Two restarts of GDS1
