ERC-165

[jmank88]

ERC-165 "Creates a standard method to publish and detect what interfaces a smart contract implements."

Explorer should check if a contract implements 165, and if so it should utilize supportsInterface(interfaceID) to check for any common interfaces that can be used (e.g. ERC-20).

Related to (and probably blocking) #212

Each call costs up to 30,000 gas, so this may not be a scalable option.

@jmank88 extracted interfaces from bytecode

@bergauz This is an alternative to ERC-165, correct? We can't actually use it for free?

[bergauz]

@jmank88 @treeder since we are getting interfaces from bytecode -> #242, if needed we can store interfaces that contract supports to db and show them in contract page, smth like #176

@jmank88 @treeder closing?
