Make scroll-wheel modifier keys consistent in editor summary pane.

Browse source 
Separate out the handling of left/right scroll events from normal up/down
ones in the editor summary pane scroll wheel handling, and use the new
constants for scroll wheel keyboard modifiers in conjunction with up/down
scroll events. Modifiers for left/right scroll events should be unaffected
by this.
