Changed program name to bmorse  (b stands for bayesian).
Cleaned up all files and changed morse.h tp bmorse.h

2013-DEC-29
	Added more options to enable debugging and testing bmorse decoder while using WAV audio files as source.
	Bit filter (-bfv) option does envelope smoothing - 10 msec rise time assumption based on experiences with FLDIGI.
	Plot option (-plt) enables piping such as  "bmorse -plt <sndfile> | xplot" to visualize the CW envelope.
	AGC  option (-agc) has fast rise and slow decay in case original signal has very large dynamic range.
	AMP option  (-amp) allows to multiply envelope signal with a constant.
	DUR option  (-dur) allows manually to set Bayesian decoder sample duration (used in path.c).
	FFT option  (-fft) enables either FFT based signal recovery or just low pass filtering.
		- FFT has also peak_detection() to find if there are multiple signals in the audio frequency range.
		- Parameter "delta" sets peak detection threshold
		- Width (-wid) and length (-len) parameters can be used to set FFT size and chunking
Added bmorse.c and bmorse.h (they are renamed from morse.c and morse.h)
