Adds the functionality to download search results on twitter.com/search. Since twitter only allows downloading of up to 3,200 of a users most recent tweets, you will be unable to download old images from users with a lot of tweets. To bypass this, you can use the twitter search to get the tweets from the sections in time you were stopped at. An example search would be "from:user since:2015-01-01 until:2016-01-01 filter:images". The URL you would use will look something like this https://twitter.com/search?f=tweets&q=from%3Asupernaturepics%20since%3A2015-01-01%20until%3A2016-01-01%20filter%3Aimages&src=typd&lang=en
The _tweets_from_api function had to be changed because it would not get the next page of results using the last "data-tweet-id". It would return the same JSON but with a "min_position" string added. Using this string for the "max_position" param from the second page onwards correctly returned the next pages. This change does not interfere with how the other extractors work as far as I know. The 2 regex patterns in the extractors had to be changed to not match the search URL.
- let the GalleryExtractor class inherit directly from Extractor
- make ChapterExtractor a subclass of GalleryExtractor
- change enumeration field names of GalleryExtractors to 'num'
The Patreon-provided URLs for the next set of posts aren't
always complete, i.e. they can be missing their scheme and
the subsequent double slash: "www.patreon.com/…"
Some galleries return a 404: Not Found error when trying to access
them through the main gallery URL, but their content is still
available on the respective /reader/ page.
... except for sta.sh content.
Instead of using the old '/api/v1/oauth2/deviation/download' endpoint,
which started delivering URLs to 404 pages a while ago,
it is also possible to get a download URL from the relatively new
'/_napi/da-browse/shared_api/deviation/extended_fetch' endpoint
used by DeviantArt's Eclipse interface.
The current strategy is therefore:
- Iterate over deviations using the OAuth2 API
- Fetch original download URLs with the new NAPI/Shared API
- provide a 'user_name' metadata field
- usually the same as 'artist_id', except for favorite downloads
- extract the whole description text and properly escape HTML entities
- fixed an issue with titles or tags containing double quotes
