[NGRM] - enhance WLV and SLV controller mechanism

[mirisb]

Missing event handlers for SyncLogView (onSomethngHappened CB) - We would like to be notified about mouse events that occur on a specific track on a specific well (specific controller)

Required notifications is for mouse click:

1. What mouse button was used - MB1 or MB3
2. type of click - mouse down, mouse up, double click
3. Where did this click occur - which well (indicated by the controller), which track in that well

In addition, we need notification when a controller is removed. currently we only get notified when a controller is created.

This issue relates to #2108 in which we request a way to ask the controller if it is completely mounted yet (i.e. visible).
