Wialon App Functionality

We looked to move from our current use of GPS Tag to the new WiaTag only to find we would lose a well used function that our clients use quite a lot and have come to rely on. (Also is a good selling point)

2-way messaging via Chatterbox -- is available in GPSTag but not WiaTag although driver can still send images.

This 2-way communication function via the GPS Tag app (not sms) needs to be added so driver can send messages to dispatch and vice versa.

If this was added then WiaTag would be able to replace GPSTag, but currently is a backward step.
