I added a timestamp option into the filenames argument

[deganii]

Hi Ted,

Thanks for your great work on this simple and useful webcam image capture app.

I made a small modification which allows a user to specify a wildcard {TS} that is replaced by a timestamp. So for example:

CommandCam /filename C:\my_photo_dir{TS}.png

Would expand automatically to:

CommandCam /filename C:\my_photo_dir\2017-10-30_02-30-12.png

I found this very useful for saving timelapse photo sequences by periodically calling the above command from the windows task scheduler. If you think it's worth adding to the main repository, please feel free to modify as you see fit. Thanks again!

Best,
Ismail
