Add the Diamond Standard to the list

[Nick Mudge]

I think that the Diamond Standard should be added to the list. It should be added to the Upgradeability section and to the contract standards section.

"A diamond is a set of contracts that can access the same storage variables and share the same Ethereum address."

The Diamond Standard is here: ethereum/EIPs#2535

Here is an example of a tool (in Python) that helps manage diamonds: https://github.com/lampshade9909/DiamondSetter
