Fixed near range issue for carriers. now the infantry disappearance range for boarding is calculated by the carrier bounding range, which is derived from the bounding rectangle on the Y-axis. The near range parameter can still be provided and will be interpreted as the loading range for static cargo objects!
Fixed messaging. Now a message is shown when cargo reports itself when in LoadRange and when near, it will allow for loading of cargo.
Fixed the perception that cargo can be boarded when loaded in an other carrier, which is totally wrong.
