Some customizibility for control scheme.

[cantcodetho]

No biggie but would be nice to have couple settings available for the way you control/navigate.

First would be nice to have an option for selection box to select things that it partially overlaps instead of requiring to entirely cover node in order to select it.

Second, have an option for left mouse button to default to box select instead of pan. Middle mouse button is panning already anyway.

Why that request? Because that is default behaviour of other apps for example Unreal. Gives consistency when alt tabbing between them.
