ensime-sbt-cmd for sbt 0.13

[Dmitry Bushev]

Hi,

I played with 0.13.0-M1 sbt release and adapted ensime plugin to this new version, also fixed some deprecation warnings. Don't know if this worth creation of separate branch in original repo.

Hi, that's cool! Did you update this for later 0.13?

It would be cool to have the plugin cross-build if possible, I think many authors do that.
Otherwise, a separate branch would be appropriate IMHO for as long as both releases are maintained.
