Add an option to download each article separately as a PDF in GUI

[ZER-0-NE]

This would come as a separate option to download all (or preferably 10-20) articles in PDF form with the name of file as the title.
The first line would contain the URL of the article (just in case the user wishes to see in his browser). The article would begin from the next line.
This can be done as a separate script at first and then later integrated with the GUI.
