A Config Option to Not Retrigger Analysis when Reclicking on a Move

[psygo]

If I click on a move for the first time, analysis is triggered, and, if I go back some moves, and happen to later click on that same move again, analysis is run again on that move. I find this a bit unnatural, since I expected analysis would be skipped given we've already done it.

If the user wanted more analysis for that move, I think it would be much more natural to have him press space instead. Could there be a settings option for changing this behavior?
