[config] allow specifying input file inside the config

[allendema]

$ cat ww.json

#
"base-directory": "ww",
"input-files": ["~/urls.txt", "./relative.txt", "file_in_basedir.txt"]
#

So that for each specified file, --input-file $FILE is implied.

gallery-dl --config ww.json

Uh, what? This is completely backwards.

Besides, simply use a shell script for something like this, automatically calling gallery-dl with different configs, different input files etc. pp.

[allendema]

Sure. Its just to conveniently have everything configured in the config file and not a real problem.
Like yt-dlp which allows --batch-file FILE in its config.

I've added a global input-files option (b46169c). Is this good enough? Should I change anything?

edit:

Additional# input files.

[allendema]

No changes needed, it does everything nicely.
Thanks. 🤖
