Enhancement: Before/After lock-unlock (see issue 1017)

Browse Source 
Lock: keep the Before view unchanged -
useful to evaluate the cumulative effect of multiple tools.
Additionally, comparison can be made to any state in the History

Unlock: the Before view will follow the After view 1 step behind,
showing image before the effect of the currently used tool
