Leginon

From the time speed up additions to Leginon, focusing was made to use the last image from drift check for focusing. When drift check is disabled, the Focusing node knows to create a new image.

This is fine in normal Leginon, but in Leginon RCT, the RCT node makes a drift check, but then as it passes to the Focusing node without dirft check it uses the old drift check from the RCT that has changed since moving to the focus node.

Only Jim can fix this in a reasonable amount of time.
