Erik Hofman:

I changed the sound code to let it use FGCondition. This changes the
code and configuration files rather drastically. Furthermore I've added
an in-transit mode which plays the sound only when the tied property is
changing.

Changes:

Code:
* Added condition support to trigger an event
* Removed the <type> section from the main event definition
   (this could be done using conditions)
* Removed the abillity to use several events with the same name,
   instead it is required to use conditions.
* Updated the README.xmlsound

Base package:
* Changed the configuration files accordingly.
* Changed flaps and gear to use the new in-stransit mode.
* Changed the flps.wav file so it can be looped.
* Created a new gear.wav file (whcih can be looped)
   and a gear-lck.wav file for gear locking sound.

IMPORTANT:
To change existing configuration files to the new ones, it is important
to pack events with the same name together into one singel event, using
the condition specification. Also, when using special types (inverted,
flip-flop, raise or fall) these should be changed to a conditions also.
For more information, please look at
FLightGear/docs-mini/README.xmlsound and the supplied aircraft
configuration files located under FlightGear/Aircraft (espesially
c172/c172-sound.xml and c310/c310-sound.xml).
