Pan map with Left Mouse Button

Add an option to pan the map when holding the left mouse button.
Using the left mouse button to pan feels more intuitive and natural to me. I tend to right click to de-select frequently, so this shouldn't be an issue.
Generally speaking, if some players prefer one type of control system or game mechanic etc and other players prefer another one, make both\all available and selectable in the Settings menu.

This would be another answer to the problem of deselecting the item that is currently selected when trying to pan the view. Holding the Alt key to prevent this when dragging the view is annoying.
And while we are discussing the control settings for keyboard and mouse. It would be nice if all the control settings for everything is displayed somewhere. The ingame note on keyboard settings is not complete. Maybe in the Wiki and/or a pinned thread in the Steam Forum?
