* 050525 Path form Alberto Jaspe (videaLAB / University of La Corua)
  - Several miscelaneus bugfixes.
  - Added support for reading/writing from/to osg files.
  - Important bugfixes in doppler issues.
  - Using just one update frequency for listener and sources, in SoundManager.
  - Using a state for clamp function for max velocites in both listener and sources,
    disabled by default.
  - Replaced the FilePath Manager for the osgDB support.
  - Added a new example called osgalviewer, that acts like osgviewer, but with some features oriented to treat with Sound Nodes.
  - Compiled and tested with OSG 0.9.9.

* 050208 Patch from Loic Dachary applied. Mostly buildstuff.

* 050113 Fixed bug in SoundManager. Crash during call to shutdown if there were soundstates 
  left in the active queue

* 041110
  - 041110 OpenAL++ now uses its own ref_ptr, this means that the responsibility of
    deleting Sources Samples etc. have been resolved. 
  - A new example osgalmultiple example demonstrates this.
  - A few method have changed semantics:

     //The last argument now specifies if getSample()/getStream() should add any found and loaded samples/streams
     //to the cache for faster access later on.
     SoundManager::getSample(const std::string& path, bool add_to_cache=true );
     SoundManager::getStream(const std::string& path, bool add_to_cache=true );

     SoundManager::clearSampleCache()
     SoundManager::clearStreamCache()

     now takes care of cleaning the caches.

  - SoundManager::clean() is deprecated and replaced by the method shutdown().
    shutdown must be called prior to end of main() function. Otherwise OpenAL will cause
    problems during deallocation of sources later on.


* 040621 Fixed bug in SoundRoot. Now uses correct modelview matrix.
