Logging in automatminer with Windows

[Emily]

Hey! 

In the utils/log.py initialize_logger function, the log file name is set to have %H:%M:%S - in Windows file names can't have the ":" character in them so it throws a FileNotFound error. I just changed them to "-" and it works fine!

Thanks!

Hey thanks for letting us know! We will change this to support Windows as I don't believe it will impede *Nix users whatsoever.

Thanks,

Alex
