Bug in MicroBird/MedSAFE tracking device files. (core\igt\igttrackingdevices\)

Calling the destructor ~TrackingDeviceSource leads to the call of
TrackingDeviceSource::Disconnect();
which then calls MedSAFETrackingDevice::CloseConnection();

In this CloseConnection(), the members m_TransmitterConfig and
m_SensorConfig are deleted but NOT set to NULL.
if (m_TransmitterConfig)

delete [] m_TransmitterConfig;

if (m_SensorConfig)

delete [] m_SensorConfig;

This will be also done by the destructor of the tracking device, in this
case ~MedSAFEtrackingDevice(); which , if I'm not mistaken, always is
preceded by the above CloseConnection(); call .The condition "if
(m_TransmitterConfig)" stays true and delete will be called again even
if the array is already deleted. Hence m_TransmitterConfig and
m_SensorConfig have to be set to NULL within the
MedSAFETrackingDevice::CloseConnection(); or the member array deletion
has to be removed completely.

The same problem subsists in the core code of MircoBird and should be
changed.
