Fixed broken section of The Age recipe

[pshute]

Since I started using it several months ago, The Age recipe has always included a rogue section containing the whole main page of the site. I suspect this has happened because they changed the link to the main page at the bottom of the text only page from a relative to an absolute path.

Once fixed, it reduces the size of the resulting ePub from 1.3MB to 0.6MB, and the download time from 2.5 minutes to 0.5 minutes. I changed:

                title = self.tag_to_string(tag)
                sections[section].append({
                                 'title': title,
                                 'url'  : url,
                                 'date' : strftime('%a, %d %b %Z'),
                                 'description' : '',
                                 'content'     : '',
                                 })

to

                title = self.tag_to_string(tag)
                if url != 'http://www.theage.com.au':
                   sections[section].append({
                                 'title': title,
                                 'url'  : url,
                                 'date' : strftime('%a, %d %b %Z'),
                                 'description' : '',
                                 'content'     : '',
                                 })

Not sure if this is the most efficient fix, but it seems to work.
