Provide a solution to export one page in a file

[kelson42]

• One button should be displayed on each page
• Clicking on the button should generate a ZIP file on the fly and propose the user to download it or even better directly open the email client to send the file in attachment
• In the ZIP we should find:
  ** All the articles images in high resolution
  ** The wikitext of the article
  ** The HTML code of the article (corresponding to the wiki text).

@Anthere You confirm this is the kind of thing you would like to see implemented?
