Add SHA256 and LICENSE for KREW

[shpwrck]

I changed the Makefile to conform to the Krew standards:

• Top Level Binary
• Include LICENSE

I also added the sha256 for ease of use.

I've read through this: https://github.com/kubernetes/kubectl/issues/964 and I realize that this will probably become core functionality, but I want it in krew until that happens.

I've already tested it using the following krew index.

"plugins/blame.yaml"

I saw this on https://cncn.io and I would like to make this available to the krew user base.

Can you make another release so that I may reference it in a krew plugin?

@shpwrck v0.0.3 is released now.
