Placeholders in auto_fire_on_unexpected_ball

Change auto_fire_on_unexpected_ball to template_bool in ball_device

[RoseAndres]

To clarify, this is just changing the name of a variable, correct?

It should change the type of the variable in core/config-spec.py (from bool to template_bool). Templates are evaluated at runtime. Therefore we have to call evaluate() on usage of the variable (probably only one or two places).
