FlightGear - Flight Simulator FGAddon

Stereo sound file bug fixes for the A340-600.

This follows from http://thread.gmane.org/gmane.games.flightgear.devel/77932.
With the introduction of the 3D sound engine, all sound files in FlightGear now
must be mono point sources.

The following original sound files have been preserved by renaming to
*-stereo.wav, as the information content in both stereo channels are similar but
non-identical, and mono versions created by extracting the left channel:
- Sounds/Flaps.wav
- Sounds/captain.wav
- Sounds/cruising.wav
- Sounds/decending.wav
- Sounds/emergency.wav
- Sounds/tenthousand.wav
- Sounds/whine2.wav

The following sound files have been converted directly to mono, by extracting
the left channel and overwriting the original file, as both stereo channels
contain identical information:
- Sounds/music2.wav
- Sounds/seatbelt.wav
- Sounds/touchdown.wav

The following sound files have been split into a *-left.wav and *-right.wav
positioned at [0, 5, 0] and [0, -5, 0] respectively, and the original file
removed:
- Sounds/music.wav

EC130 B4: one missing texture file added by Michael Habarta

BO105: Accidently named it wrong in the -set.xml. Looking at the 3d-model and the yasim.xml it is a BO105 CBS, and not a CBS5.
