Feature request - publishM2

It's a small change including a publishM2 action. Currently the sbt-native-packages only supportspublish and publishLocal actions.

Solid pull request 😎

Thanks for improving sbt-native-packer. This looks like a reasonable extension. We'll merge when the tests have passed.

How can we deal with this travis error at .m2 directory, when it is building a package at second time?

[info] [error] java.io.IOException: Destination file file:/home/travis/.m2/repository/simple-test/simple-test/0.1.0/simple-test-0.1.0.zip exists and overwrite == false

Similar problem:

Workaround:

add isSnapshot in ThisBuild := true

or

change version := "0.1.0" to version := "0.1.0-SNAPSHOT"

Sorry for my last (now deleted) comment. I haven't seen your last comment, which already addressed this issue.

I would go isSnapshot in ThisBuild := true and put a small comment in there why we need it.
