Fix & complete contract ABIs, export Typechain contract types and factories

[jfschwarz]

This PR adds the correct ABIs for all zodiac module contracts. It also sets up Typechain so the @gnosis.pm/zodiac will now export interfaces and factories for all our contracts. This should make this package more useful when building apps on top of our contracts.

While doing this wholesale review I couldn't resist clearing out some inconsistencies in the names of some of the existing exports:

• removed the interface formerly exported as ContractAddresses (which is not used anywhere afaict)
• renamed export: SUPPORTED_NETWORKS -> SupportedNetworks
• renamed export: CONTRACT_ADDRESSES -> ContractAddresses
• renamed export: CONTRACT_ABIS -> ContractAbis

All of these are BREAKING CHANGES meaning we must publish this as v2.0.0.

We could even setup typechain to export fully typed ethers contract factories for our contracts.

Yeah, I really like this idea.

Sounds great. I also noticed this problem when adding new known contracts. I ended up adding the "raw" ABI here: https://github.com/gnosis/zodiac/tree/master/src/abi and importing them https://github.com/gnosis/zodiac/blob/10b6ca9c450143736395b1ff2e0b769a9e669f8e/src/factory/constants.ts#L274-L276.
It probably makes more sense to add the full .json ABI file (like you propose) instead of the way I did it to make it easier for Typechain.

Nice work.

There is only one thing; the old factory file (src/factory/factory.ts) is added back in. The functionality that was previously in that file is now improved/updated and is in the moduleDeployer file (src/factory/moduleDeployer.ts). Perhaps we can just remove the factory file (src/factory/factory.ts) again?

Ah, great catch! I've fixed it now.
