[Upp-changelog] ArrayCtrl Focus w.r.t. WhenEnterRow and WhenCursor by mouse click....

[<cx...@nt...>]

...now inside callbacks, if respective callback was invoked as the 
reaction to the mouse-click, ArrayCtrl already has Focus set.

(this is important in some specific situations like two ArrayCtrls, 
positions of cursor in one is changed when user changes cursor in 
another - symetric).
