Reorder front end to collect smart contract address first

[fulldecent]

Currently, the tool only validates ERC-721 contracts. We will expand the scope of the project, so the UI should also be compatible with doing multiple test suites.

New web page format follows:

Smart Contract Validator

This validator tests blockchain smart contracts for known vulnerabilities and conformance to published standards, including ERC-721 Non-Fungible token standards.

INPUT A VALID CONTRACT ADDRESS:

[ INPUT: ADDRESS ]

SELECT A NETWORK:

[ DROP DOWN:

A smart contract exists at address, it is XXXX bytes.

The contract supports the following known interfaces (testing with ERC-165):

[ A bunch of labels. Supported interfaces are lit up and show first. Other interfaces are dim and shown after ]

Choose test suites to perform:

• ERC-721 Non-fungible token
• ERC-20 Token (COMING SOON)
• ERC-777 Token (COMING SOON)
• Known Solidity bugs (COMING SOON)
• Make your own test case (COMING SOON)
