Counter not working, plus date based folders

[Mohoganogan]

The limited number of exposures was not working, and I added the ability to create a date based folder in the chosen directory.

Below replaces lines 94 - 106

snapcounter = 1
i = 0
while True:
rightNow = datetime.datetime.now()
newpath = r'/mnt/usb/pictures/%04d%02d%02d' % (rightNow.year, rightNow.month, rightNow.day)
if not os.path.exists(newpath):
os.makedirs(newpath)
fullfilename = "/%04d%02d%02d/%04d%02d%02d-%02d%02d%02d.jpg" % (rightNow.year, rightNow.month, rightNow.day, rightNow.year, rightNow.month, rightNow.day, rightNow.hour, rightNow.minute, rightNow.second)
fullfilename = os.path.join(args.p, fullfilename)
cam.capture(fullfilename)
cam.stop_preview()
if args.n == 0:
logging.info("Taking snapshot ({} mode)".format(mode))
else:
logging.info("Taking snapshot ({} of {}, {} mode)".format(
i + 1, args.n, mode))
i = i + 1
