Add settings to pan canvas editor with scrolling

Browse Source 
This feature is mainly designed for developers who uses touchpad instead of mouse, and want to scroll instead of zoom. Every macOS developers will like it since it feels intuitive.

2 new settings are added to “editors/2d”:

scroll_to_pan: turn on to use mouse/touchpad scroll to pan canvas item editor view instead of zoom
pan_speed: use this value to change scroll speed
