This commit changes how users can interact with handles: Unselected handles are not drawn anymore by default. Handles are bit thinner. If handle can't be selected, because strip is too small, it is not drawn. When hovering over strip handle a cursor is changed to represent a handle shape. It is possible to select 2 handles at once if strips are adjoined. When tweak event happens on unselected handle, handle selection is lost ater tweaking. This behavior can be disabled in preferences: Editing > Video Sequencer > Tweak Handles. Moving strips with G key works same way as before.
