@roysc @i-norden Please ignore /x nameservice,bond, and auction modules , those already reviewed
Please review middleware code and remaining changes

Mostly just needs some cleanup. Also should have some TODO comments for things like the commented out IBC code in app, or anything else that's not fully refactored or removed.

LGTM! Of course- unfortunately- we will need to perform another refactor of our SDK branch, cut a new release, and perform another refactor here soon since the SDK is reverting to ante handlers...
