ZeroDivisionError: float division by zero

[Hiromi-nee]

I can't seem to figure out why there's a divison by zero error.

The error occurs in the conversion of gps info from exif tags: https://github.com/saimn/sigal/blob/master/sigal/image.py#L180
So you must have exif tags with 0 values in the GPSInfo field.I will add a check to avoid breaking in this case.
