    tools/bsefextract.cc: Increase output format precision of some features.
    
    Sun Jan 10 14:03:07 2010  Stefan Westerfeld  <stefan space twc de>
    
    	tools/bsefextract.cc: Use double_to_string() for output formatting
    	of the --raw-signal and --complex-signal features. This increases
    	the output precision, and therefore should be appropriate even for
    	24-bit signals (which the original %f format wasn't).
