Right-clicking on white shouldn't set color

[rywal]

Right clicking on the white background currently sets the user's color to white, which may cause confusion for users who attempt to draw on anything that is not colored(i.e. the background). Logic should be added to prevent changing color if the color is white

gridClicked(square)
var user.color = (el.backgroundColor !== ' ') ? (server.color) : (user.color);

wrong variable names but you get the point real simple fix.
