Return iovns version info in abci_info

[davepuchyr]

iov-one/weave#1194 was a really helpful feature that should be incorporated into iovns

Apparently we don't need extra implementation for this. Cosmos SDK handles it. Check related the configuration code:
http://github.com/iov-one/iovns/blob/4eacb6792f772669e4c6593a63949b8747a6f7d4/Makefile#L3-L12. Let's keep this issue here until we have a node running and test the issue.

{
  "jsonrpc": "2.0",
  "id": -1,
  "result": {
    "node_info": {
      "protocol_version": {
        "p2p": "7",
        "block": "10",
        "app": "0"
      },

      "network": "iovns",
      "version": "0.33.0",

...
I believe that "app": "0" means that we need the tech from iov-one/weave#1194.

@orkunkl, let's construct the app version info as 10000 * major + 100 * minor + patch, so v1.93.4 would yield app version 19304, for example.

I've made the implementation on cosmos-sdk but I'm sure even if we get this PR approved, it will take time to get this feature released soon. So instead we should fork cosmos-sdk as private repo and merge the changes there. @davepuchyr can you?

Let's wait until it's publicly announced that we're using cosmos-sdk.  I didn't know that it would be such a big deal to add this nice to have feature.  I know that it's unsatisfying to leave work in a "pending" state, but we want to stay in stealth mode until we can deliver to all of our stakeholders.
