Avalanche(AVAX) Avascan Transition

The current version of Snowtrace by Etherscan is being sunset and replaced by a new version run by Avascan. Users will continue to enjoy a similar interface, URLs and APIs they're currently using, now supporting the C-Chain and all Subnets. A demo is already available at http://Snowtrace.dev. The http://Snowtrace.io domain will still be live and transition fully to Avascan on Nov. 30th with no disruption in services.
