Alternate move controls

[lightvector]

Implement or experiment with alternate controls for moving pieces, such as edge-clicking or drag-and-drop.

Pushes and pulls could be more efficient if you move the enemy piece first.

It would be cool to have keyboard controls for power users. For example, type "H" to highlight your horse, then press "H" again to switch to the other horse. The arrow keys or WASD could be up-down-left-right. I imagine this could be much faster than using a mouse, so it would be great for blitz games. Off the top of my head, I don't know how keyboard controls should work for pushes, pulls, and rabbit steps.
