migrate is no longer supported

[nfisher]

See issue #311 where @mattes states;

Everyone,

I started migrate 3 years ago and I'm happy it's seeing widespread adoption. I see forks at @99designs, @codeship, @uber, @segmentio, @newrelic, @gitGNU, @postmates and many more who find migrate helpful and try to help pushing it forward.

Some months ago I co-founded www.templarbit.com and ever since things are busier than ever. It's unfortunate, but I won't be able to keep maintaining migrate.

Who is interested in stepping in and taking migrate over?

The most active successor seems to be this;

https://github.com/golang-migrate/migrate

Thanks @mattes for your efforts in bringing it this far! 👍

@mattes thanks for the effort! Maybe it should be clearly stated in the README.md and in awesome-go :-)
