once Project Token Address is provided, it should fetch the data from the etherscan or etherplorer. If we are only able to use ERC20 tokens, we should state that as a warning (in tooltip).
It should fetch and display the token name, ticker, token standard, the token logo and the maximum project token supply. Each of these things needs to be also manually provided if we are not able to pull the data.
Further to validating project tokens for their implementing ERC20, per @renc-curvelabs we will require that project tokens be verified on etherscan.io. This need only apply to mainnet, not rinkeby.
