Cosmwasm 0.16

Closes #246
Closes #239

[webmaster128]

Could you close #239 in this PR too? IIRC we added test events in one of the development contracts that we can inspect in Go tests.

[webmaster128]

Looks good. We just need tests to check we get those events in Go:

    Ok(IbcBasicResponse {
        messages: vec![msg],
        attributes: vec![attr("action", "ibc_connect"), attr("channel_id", chan_id)],
        events: vec![Event::new("ibc").attr("channel", "connect")],
    })

and

    .or_else(|e| {
        // we try to capture all app-level errors and convert them into
        // acknowledgement packets that contain an error code.
        let acknowledgement = encode_ibc_error(format!("invalid packet: {}", e));
        Ok(IbcReceiveResponse {
            acknowledgement,
            messages: vec![],
            attributes: vec![],
            events: vec![Event::new("ibc").attr("packet", "receive")],
        })
    })

I was already working on that :D

[uint]

I think we're good!

[webmaster128]

Nice. Let's release that as wasmvm 0.16.0-rc1 for integration in wasmd
