Remove Web3.js injection dependency [BOUNTY $100]

[fulldecent]

Tenthousandsu.com currently relies on MetaMask's injected Web3.js dependency.

This approach is no longer recommended by MetaMask and is not compatible with Opera.

Apparently it is "simple" to do. But I can't find documentation of the canonical way to do iit.

Requirements

• Makes the current tenthousandsu.com website work on Chrome+MetaMask AND iOS+Opera
• Loads Web3.js from a reliable CDN that many other people are using
• Does not change build process (we will not switch to npm for this)
• Minimizes impact on existing code

Not sure where you are seeing expired. But this issue here and my commitment to pay this bounty is active.
