Human-readable names for saved files

[robertf]

I'm not familiar with your radio-scanning application and have just been looking for a open-source sound-activated audio recorder for Windows that produces time-stamped files, to spy on my cat. Is there a particular rationale for using UNIX timestamps as file names rather than human-readable names like yyyymmdd-hhmmss? I've modified the source code to give the latter behaviour, which is more convenient for me. I have no experience with forks and pull requests, the change is trivial, and I don't know if this feature is even desirable, so I'll just present the changes here:

		secs = int(fname[:10])	#R
		fnameMP3 = time.strftime("%Y%m%d_%H%M%S",time.localtime(secs))+".mp3" #R
#R		copyfile(fname,'./audiosave/'+fname)
		copyfile(fname,'./audiosave/'+fnameMP3)

Thank you for making this nice application available.
