#4 OpenTrac patch for listen utility

[Remi Chateauneu]

Please see here : http://www.opentrac.org/ , an
APRS-like protocol.

"OpenTRAC stands for Open Tactical Reporting and
Communications. In short, it's a message protocol
designed for carrying tactical information, including
GPS position reports, weather data, and telemetry, over
an unreliable, bandwidth-constrained network.
Typically, this is the Amateur 2-meter VHF band using
1200 bps AFSK. The protocol is specifically designed,
however, for use across multiple networks to support
Internet backbones, satellite links, and so on."
