Noted that it only picks circuits and stackable items, 'refilling' the inv.

For peace of mind, maybe only picking up circuits and ignoring all items is a
better approach. Then the label would be "auto-pick circuits".
After all, a slowdown was also noticed during playtest. 


Unrelated note: A SIGSEGV was also reported but I had multiple patches attached
and it is not possible to determine the reason. (I got rather used to receiving
random crashes with no explanation or whatsoever.)
No other bug was found.
