#1489392 - arrow key with control down should *not* select messages

In alignment with desktop applications (windows & mac) using the arrow keys with the control key pressed should not select the messages.  Changes code so that with_mouse will be passed as true when click event occurs, and row will only be toggled if it was a click event.
