/* eBay - Display Totals with Shipping
Created : 20/07/06

Change log:
1.0.0 29/07/06 Initial Version (User 2042)
1.0.1 22/03/07 Modified - works with bug fixes, Ebay UK, proper extra column, SORTS!
1.0.2 27/03/07 Now caters for ebay.de (EUR) and sorting works for mixed currency listings (assuming £1 = EUR 1,50)
1.0.3 28/03/07 Now caters for ebay.com ($), assumes £1=$2. Also, heavy clean-up of price columns analysis - instead of wondering through spans and other tags (which may change, if EBay change format), use TD's textContent with a regular expression
