- Removed Maxime cache system (sorry mate!) and now using a standard Osc cache system base on the product/language & currency. For this cache I also made use of contribution http://www.oscommerce.com/community/contributions,5108 that rewrite the tep_reset_cache_block function in a more efficent manner.
- Added 2 indexes to the xsell table creation.
-Removed reference to enable/disable categorie & SPPC as well as unused files.
- Optimized the module queries by using outer join and removing call to the tep_get_products_special_price.
- Included a fix found on the forum for the redirection when clicking on the buy_now button on a linked product.
- Changed Admin Xsell to display images on all pages. Also fixed problem with image path that could link to always display "No images"
- Xsell admin Price is now shown including tax as well as specials price if exists.

Tested on 2.2RC1
