v0.2 - 2004-12-01

+ added set_link_referrer() method as a more generic
  forward-looking replacement of set_amazon_id() (deprecated)
+ added an overriding URL field for all links (in case you want
  a link somewhere else)
  NOTE: you will need to "install" the datbase table again - no
        data should be overwritten, but backup your WP database
        anyway, it's good practise!
+ added a set_limit() method to limit the number of items per list
+ added a set_title_element() method to define the header element
  used on lists (defaults to div)
+ added a set_list_type() method to set the type of list to create

- deprecated the set_amazon_id() method

~ changed the list format, from nested unordered lists to unordered
  lists with a (by default) DIV header element (requested by deadgoon)
~ added some defensive coding to all methods
