===================================================================

Version History
---------------
1.3   - Added plugin options page so users can update the default country, 
        associate ID, and subscription ID without modifying the plugin source.
      - Added a “check for update” feature that allows users to easily see if their plugin is up-to-date.
      - Dropped support for 1.2.x
1.2.8 - Changed the Amazon Link on the edit page to be a button in the
        Quicktags region.  Allows for WP-Amazon to work with the Tiger
        Style Administration plugin.
1.2.7 - Added some inline CSS to hide the admin header
1.2.6 - Added Added Michiel Maandag's enhancements 
        (http://wordpress.org/support/topic/32412)
1.2.5 - Fixed code that checks if curl is installed.  By default,
        curl is preferred, but if your host doesn't have it installed,
        it downgrades to using fopen.
1.2.4 - Added support for WordPress 1.5.  Still supports 1.2.x.
      - Relocated wp-amazon.php to the plugins directory.
1.2.3 - Added support for Amazon ECS 4.0 France and Canada
1.2.2 - Added check to see if magic quotes is turned on or off.  This was
        causing a JavaScript problem with servers that had magic quotes turned
        off.
1.2.1 - Replaced htmlentities to htmlspecialchars to support special characters
        in Japanese and German
1.2   - Upgraded to Amazon E-Commerce Service 4.0
      - Removed dependency on NuSOAP and moved to using standard PHP XML support
      - Added ability to change the Amazon country site to search form
1.1   - Cleanup
1.0   - David Schlosnagle's blended search has been included (thanks David!)
0.92  - Removed target="_blank" and properly encodes entities to preserve
        XHTML compliance.
0.91  - Reworked search features. Removed search by and replaced with product
        line search field.  All searches are now by product.
      - Added support for Amazon UK, Amazon Germany, and Amazon Japan. Needs
        to be thoroughly tested still.       
0.9   - Initial release
