Log of user activity: additional info about unit in run

[selinakreinhard]

In Users-> log of user activity, I would like to have an additional column between "Unit in Run" and "Session", giving the name of the unit, so it gets easier to understand where my run does not work the way I intended it to do. In a more complex run, position and kind of module (e.g. survey) are not very informative (I have a lot of modules of the same kind and do not know what position translates to which module name by heart).
