Release for Scala 2.10/2.11

Hi, your plugin seems great. I'd love to try it out.

When I try to use this, I get this output:

It seems it needs the 2.10 version, but maven central only has the 2.9.2 version with sbt(?) version 12 (see https://repo1.maven.org/maven2/com/github/shivawu/). Is it possible to release this version to maven central?
