Update registry assets to simple solidity registry implementation

[njgheorghita]

What was wrong?

New simplified solidity registry implementation [here] is the default registry implementation moving forward. ethpm's assets folder needs updating to use this implementation.

I'm inclined to have you get 1-2 more people to look at this before merging just because it's smart contract code. They don't necessarily have to be solidity experts but more 👀 might catch something I missed.

maybe name _cutRelease to signal privateness.

Should this be pure?

[njgheorghita]

Yes, it should. But the ERC / Interface define this function as view. Which looks to be the case b/c in the complex solidity implementation, it generates these values via the PackageDB and ReleaseDB. So, I left it as view here to maintain compatibility with the erc/ PackageRegistryInterface.

weird indentation

Yup, doing that in ethpm/solidity-registry#1. The contract here is v2.0.0a1 - and will be updated to a stable version once ethpm/solidity-registry#1 is approved/merged.
