Update BCH logo to advertise EVM capability.

It seems nobody outside of BCH is talking about smartBCH.

I try to mention it on various Youtube channels but get zero response.

Clicking on BCH in Coingecko or Coinmarketcap makes no mention of this new functionality. or links to any smartBCH websites.

A new logo with a smart tweak would be a way of getting round the news black out.
