This PR adds two options to control scrollwheel behavior.

scrollwheel_lines: How many lines to scroll.
scrollwheel_zoom_disable: To disable zooming by control + scrollwheel.

Control of vertical scrolling is taken away from Scintilla to provide consistent behavior when the control key is or is not pressed. Lines option added because I don't see a way to get or set the value used by Scintilla.

Supersedes #2954
