[Updated recipe] Ming Pao (明報) - Hong Kong (2011/02/28)

In view that Kindle 3 still can't provide perfect CJK character display and navigation experience, I've decided to have the recipe generate an e-book rather a periodical for me for the time being. Would any calibre developer help pushing this updated recipe to the next Calibre release? Thanks!

Also, the favorite icon for this recipe is http://www.mingpaonews.com/image/favicon.ico

Code:
__license__   = 'GPL v3'
__copyright__ = '2010-2011, Eddie Lau'

# Users of Kindle 3 (with limited system-level CJK support)
# please replace the following "True" with "False".
__MakePeriodical__ = False
# Turn it to true if your device supports display of CJK titles
__UseChineseTitle__ = False


'''
Change Log:
2011/02/28: rearrange the sections
            [Disabled until Kindle has better CJK support and can remember last (section,article) read in Sections & Articles
            View] make it the same title if generating a periodical, so past issue will be automatically put into "Past Issues" 
            folder in Kindle 3
2011/02/20: skip duplicated links in finance section, put photos which may extend a whole page to the back of the articles
            clean up the indentation
2010/12/07: add entertainment section, use newspaper front page as ebook cover, suppress date display in section list
            (to avoid wrong date display in case the user generates the ebook in a time zone different from HKT) 
2010/11/22: add English section, remove eco-news section which is not updated daily, correct
            ordering of articles
2010/11/12: add news image and eco-news section
2010/11/08: add parsing of finance section
2010/11/06: temporary work-around for Kindle device having no capability to display unicode
            in section/article list.
2010/10/31: skip repeated articles in section pages
