Due to API restrictions and/or missing knowledge about and
documentation of API usage, it was only possible to retrieve the
latest 200 images of a niconico seiga user with said API.
The new approach manually visits each HTML page and gets its
information from there.
This commit mostly replaces all minus-signs ('-') in keyword names with
underscores ('_') to allow them to be used in filter-expressions. For
example 'gallery-id' got renamed to 'gallery_id'.
(It is theoretically possible to access any variable, regardless of its
name, with 'locals()["NAME"]', but that seems a bit too convoluted if
just 'NAME' could be enough)
- ask user to report unexpected errors, which usually indicate
extractor failure
- handle OSErrors separately (permissions, disk full, etc)
- revert 30eef52
Use the '--netrc' cmdline option or set the 'netrc' config option
to 'true' to enable the use of .netrc authentication data.
The 'machine' names for the .netrc info are the lowercase extractor
names (or categories): batoto, exhentai, nijie, pixiv, seiga.
- The file extension of the first image had been used for all further
images
- API responses can contain invalid characters, which cause the XML
parser to fail (http://seiga.nicovideo.jp/user/illust/26377934
contains several \x08 characters)
