Integration with sbt-revolver

[liff]

Right now it seems to be possible to use sbt-javaagent with sbt-revolver like this (by stealing agentOptions:

javaOptions in reStart ++= resolvedJavaAgents.value map { resolved =>
  "-javaagent:" + resolved.artifact.absolutePath + resolved.agent.arguments
}

Would it make sense to expose agentOptions as a TaskKey to enable a nice little shortcut?

That is, something like:

javaOptions in reStart ++= agentOptions.value

If this sounds acceptable, I can submit a PR.
