scalaVersion handling in sbt plugin is broken

[szeiger]

I haven't found any way to prevent sbt from putting the containing project's scalaVersion artifacts on the benchdb classpath. This needs to be resolved before the sbt plugin will be useful and can be used the way I envisioned it (i.e. added to your local sbt setup as a global plugin, never added to a project's build definition).

Is the sbt plugin even used by anybody? The readme doesn't mention it. Perhaps we should just get rid of it?
