saugns v0.4.0b. Small usability tweaks. Language changes: * Allow 'R' without initial line type (default 'cos'). * Allow 'W' without initial wave type (default 'sin'). Change Makefile install and uninstall targets to check whether a "share/examples" directory exists; if not, place the example files under "share/saugns/examples" (more common on Linux distros) rather than "share/examples/saugns". Tweak cli code to use stdout, not stderr, for -h (help) and -V (version) options.
