Improve drag box selection logic

Browse Source 
`AllowDeselectionDuringDrag` is remove.
Instead, selected hit objects are not automatically deselected
when clock is seeked to a later time (the hit object is dead).
Update drag box selection even if mouse is not moved
(in case clock is running or scroll wheel is used).
