[webtoons] Add a new extractor for webtoons.com

[iamleot]

The webtoons extractor can extract episode and entire comic (all
episodes) from webtoons.com.

All the logic of the extractors should be trivial except for a couple
of kludges needed:

• `ageGatePass' cookie is always set to avoid possible redirect and stop of
  extraction, especially in the comic extractor
• The image URLs returned by the episode extractor could not be fetched
  directly and the `Referer:' HTTP header needs to be passed to fetch them

Close #593.

Thanks!

And a "Thank You" back to you.

There where some issues with French comic listings and input URLs without a scheme, which I've only spotted after merging. I've fixed those myself in 0378d07. Hope you don't mind.

[iamleot]

That's much better and simpler, thanks!

Is it possible to sort each episode into a folder, rather than downloading every image into 1 folder? I've been playing around with the config but can't seem to get it to work.

Sure, e.g.: % gallery-dl -o directory='["{category}", "{comic}", "{episode}"]' -o filename='{num:>02}.{extension}' 'https://www.webtoons.com/en/comedy/safely-endangered/list?title_no=352' (For possible example on how to adjust the config similarly please give a look to gallery-dl.conf(5) man page).

Hm when I try that on my pc (windows) I get the error: unrecognized arguments: URL="https://www.webtoons.com/en/fantasy/tower-of-god/list?title_no=95". I copied it exactly, not sure whats going on here.

Also, what do you mean by the conf(5) main page? Do you mean this "https://github.com/mikf/gallery-dl/blob/master/docs/gallery-dl-example.conf" ?

Sorry if these seem like obvious questions and thank you for helping, I'm not that experienced with python or cmd

[iamleot]

@doyleslee Probably the quoting of arguments (e.g.: using " instead of ') is different in Windows (and I'm completely unfamiliar with it so I couldn't help, sorry!). I'm sure others will help to shed some light!

Regarding gallery-dl.conf(5) man page I meant the man page that should be derived from here:

https://github.com/mikf/gallery-dl/blob/master/docs/configuration.rst

But probably this is not present on Windows as well, at least not in the form of a man page.

Here a possible configuration that permits to not pass the -o options before:

{
	"extractor": {
		"webtoons": {
			"directory": ["{category}", "{comic}", "{episode}"],
			"filename": "{num:>02}.{extension}"
		}
	}
}

Saved as gallery-dl.conf you can then use it via, e.g. gallery-dl -c gallery-dl.conf "https://www.webtoons.com/en/comedy/safely-endangered/list?title_no=352"

[doyleslee]

That configuration worked perfectly - thank you!

Nice!
