Fix Documentation in all places

This doesn't work as it doesn't contain main()

go get github.com/MontFerret/cli

Please update all references to:

go get github.com/MontFerret/cli/ferret

One more problem is, https://, isn't allowed:

go get https://github.com/MontFerret/cli

If it's okay with you, I will send a pull request.

Thank you.

Hey, There are several things which are outdated, can I send a pull request to update them, as I'm learning ferret?

Hey,

Sorry for the issues, I guess missed them when was extracting CLI from the main repo.
You are very welcome to create a PR!
