Fixes#4241Fixes#4242
This introduces a new subproject named scripted-sbt-redux. The purpose of this new subproject is to workaround the 'sbt.test` package vs `Keys.test` key confusion (#4242) while maintaining the forward compatibility of 0.13.17's sbt cross testing ^^ (#4241).
The new subproject uses `sbt.scriptedtest` package name, and that's the one that will be used by the mothership.
Meanwhile "scripted-sbt" subproject will also be published for compatibility purpose.
Ref https://github.com/sbt/sbt/issues/4121
sbt already has the facility to trim stack traces. This sets the trace level of the background run, which fixes the upper half of the `run` stacktrace.

The bottom half requires a similar fix to the foreground log.
scalafmt is configured to use lf, as your editor should be, so there is no point having git tinker with line endings
otherwise on checkout on windows source files get converted to crlf (by git) and on compile they get converted back to lf (by scalafmt)

This forks an instance of sbt in the background when it's not running already.
