added saved articles to be displayed if present, with possibility to …

…delete them after reading them. changed the format in which the files are saved to json

[Griffintaur]

@drusc0 any reason behind going for json?
or just because you want to store title and its corresponding url?
are you saving the articles into separate folder

[drusc0]

@Griffintaur no reason at all. But for retrieving the file and reporting back on terminal, it was easier to have a key-value pair. Is there any other format or you prefer text to cat on screen? I can make the change.
