top: TREE_FOCUS_X works properly with multiple windows

Browse Source 
As promised, this commit will ensure that TREE_FOCUS_X
impacts only the window under which an 'F' was issued.

Previously, when 'F' was invoked it would impact every
window that was displaying forest view. Now, only that
window where 'F' was applied will show the indentation
losses whenever multiple windows were being displayed.

[ each of the 4 windows can now have different focus ]
[ pids active and not impact any other forest views! ]
