Maintain revision date for "update_attribute_from_slot"

This is not a full-featured version, since it does not update the

modifying user and the modifying IP (since this data is not

always available). But this version is at least good enough

for experimenting and checking for unwanted side-effects.

Handling of mutual overwrites in answer workflows

Mutual overwrites occur in answer workflows when a user manages to

open multiple browswer instances/or tabs on the same exam.

In case there was an mutual overwrite, the position as provided by the

instance attributes might deviate from the position, based on which

the actual form data was generated. So, for validating and updating

one has to change the position to the one from the form data (when

this differs). Note that the randomizer depends on property

"position" as well.

The new version avoids that the user might accidencially overwrite his

data and closes on mutual overwrite automatically the older instance

window.
