Fix for [#31813] "bge.types.KX_RadarSensor incorrect attributes" reported by Monster.

KX_RadarSensor.angle was returning the angle that was used to construct Bullet's physics shape, which is calculated from the logic brick gui. KX_RadarSensor.angle now recalculates the original value from the gui. However, m_coneradius isn't actually used by KX_RadarSensor that I can see, so it might be better to just assign the original angle to m_coneradius instead of the calculated value. I've also made KX_RadarSensor.angle read-only, since setting m_coneradius does not appear to have any affect, which means writing to KX_RadarSensor.angle never worked properly.
