[suggestion] allow wasd keys to move field of view

Should be an easy fix. People who play on a laptops (as I do) tend to prefer the wasd to the arrow keys for moving the camera around.

I checked on the beta suggestions list and did not see this. hope I am not covering old ground, did not search the forum.

great game!

This is in the patch notes for 1.12, which is pending.

thanks!
