Description

• Improves USD estimation, which where wrong in some cases making the trade look like it had a higher slippage than it really had. If anyone notice any issue with the new approach, let us know https://chat.cowswap.exchange/
• Removes the unsupported token list, basically allowing to trade any token unless the API says it's unsupported
• Additionally, adds meta-data so CowSwap is easily indexable by bots and search engines. Includes a sitemap with the main pages.
• Handle the 0 fee case, allowing to represent if there's a 100% subsidy!
