Timeouts and retries

[Bfgeshka]

As far as I see, gallery-dl in current state cannot detect stalled download. These are vital for grabbing big galleries, so I request to add arguments for num. of retries and timeout intervals in future release.

New release is out and the features you requested should be implemented.
22910f9 really improved the way errors are handled and all exceptions that can be dealt with are caught. I'm ignoring OSErrors ("no space left on device", "no permission", etc) as there is nothing I can do about them and retrying isn't going to help either.
The timeout option gets directly used as the timeout parameter for the requests.get call (as documented here) and sets both the connect and read timeout.
The retry option effects the amount of times my own code tries to download a file. It doesn't touch the requests/urllib3 options, but I think this is good enough.

If you have any other suggestions or features you want to see implemented in this regard, let me know. Otherwise I think this issue can be closed.

Tried it out, seems working so far.

Thanks for your effort.
