Bump to sbt-remote-control dde8acfb1ef78a22b2c1a197c047f54b22fe7d44

This breaks the JavaScript, possibly because the event is no longer called LogEvent, now there is CoreLogEvent (no task ID), TaskLogEvent (like the old one with a task ID) and BackgroundJobLogEvent (background job ID).

This sbt-remote-control introduces backgroundRun and BackgroundJobStarted / BackgroundJobFinished events.

So building on this PR the JS needs fixing for the log event change, and then we can try to use backgroundRun.
