[ardour-dev] one other change in a recent CVS commit

[Paul Davis]

   * audio file naming tries to be more PT-like
       - for stereo tracks, files will be named
         trackname-<takenum>{L,R}.wav

       - for multichannel tracks, files will be
         named trackname-<takenum>[a-z].wav for
	 the first 26 channels

       - for mono tracks, files will be named
          trackname-<takenum>.wav

Note that I need to correct the logic that picks the "takenum". Right
now, its possible to have sessions containing, for example,
"audio 1-3.wav", but not "audio 1-1.wav", and on the next loading, the
new take will be identified as number "1" because no such audio file
exists. 

Thanks to Mark Knecht for the naming suggestions.
