Merge pull request #11 from typesafehub/wip/havocp-atmos-ui

Preliminary UI stuff for atmos:run
Bump launcher to support multiple sbt versions.

* Launcher now uses auto-detected scala version for both the UI and sbt.
* Launcher now reads project/build.properties for sbt version before
  dropping to activator default.
Bump sbt-remote-control version to the variant that supports sbt 0.13 + atmos.

* Use sbt 0.13.0 for launcher.
* Bump sbt-remote-control version.
Quick refactoring of SBT_VERSION property to better represent that it's just a default.
Enable console for sbt 0.13 projects.

* Bump to integration release of sbt-rc that supports sbt 0.13 + sbt-atmos
* Include 0.13 probes in build so that `activator-ui/run` works with sbt 0.13
* Remove "false" flag from run so we can test console.
