Consensus state in the wasm client

[faddat]

Currently, we're storing binaries in the repository. I'd much rather that we store the contract code here, or alternatively put the contracts in another repository, which is built in CI. I think that this would make the flow clearer. I've noticed that no PR's to the wasm-clients branch actually pass the tests for the wasm client, and I have a feeling that could be in the contract. Each one always complains of a missing timestamp field.

From looking at wasm.proto and the tendermint proto file, we can see that that tendermint has a timestamp, while in wasm, we are dealing with only a data field. I'm going to assume that the isssue is where these interact.

I think that @misko9 solved this issue, closing.

Thanks Steve!
