JLine 3: put an "RC" (a designated nightly) out for testing after worst bugs are fixed

[SethTisue]

we can recommend the usual sbt invocation for adding the resolver and setting scalaVersion

but it would be good to include command lines for running it using:

• coursier
• @dwijnand's new thing (EDIT: don't be lazy Seth, link to https://github.com/dwijnand/scala-runners)

[dwijnand]

Running my "new thing" (scala-runners) with -v will give you how to run the thing with coursier. For instance:

$ scala -v -212x -Yrepl-class-based
[setScalaVersion] arg = '2.12.x'
[addCoursier] arg = '-r'
[addCoursier] arg = 'https://scala-ci.typesafe.com/artifactory/scala-integration'
# Executing command line:
cs
launch
scala:2.12.11-bin-e1e2bfe
-r
https://scala-ci.typesafe.com/artifactory/scala-integration
--
-Yrepl-class-based

let's get scala/community-build#1116 through, then announce 2.13.2-bin-bc1cad4 for testing

note that scala/scala#8748 is merged, so -Yrepl-class-based is now the default
