Adding gx:Track parsing to the KML format. If extractTracks is true, the parser will extract points from gx:Track elements as features, acquiring attributes from the Placemark plus when, trackId, altitude, heading, tilt, and roll (assuming angles are present). r=ahocevar (closes #2771)

<p>
If a KML document contains <code>&lt;gx:Track&gt;</code>
elements and the extractTracks property is set true on the
parer, features will be created that represent track points.
Each feature will have a when attribute that contains the
value of the relevant <code>&lt;when&gt;</code> element from
the track.
