TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

Hey, thx for this module.
When I download the very same zip file from github sometimes it crashes but most of the time it works.

    download(URL, master_zip, Config.DOWNLOAD_CACHE_DIR)
  File "/usr/lib/python3.5/contextlib.py", line 30, in inner
    return func(*args, **kwds)
  File "/usr/local/lib/python3.5/dist-packages/arm_now/download.py", line 30, in download
    obj.start()
  File "/usr/local/lib/python3.5/dist-packages/pySmartDL/pySmartDL.py", line 266, in start
    self.filesize = int(urlObj.headers["Content-Length"])
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

It happens because pySmartDL assumes that webserver will always send the "Content-Length" header in its response. Some servers don't do that. In order to fix this error lot of changes are required in source code of this library.

The server I use sends the "Content-Length", as matter of fact for the same server and same file, same link, same config, one time I get an error and another time everything is fine the file is downloaded. Could it be because of some internal caching or buffering done by pySmartDL?

Fixed.
