The sbt/sbt-launcher-package doesn't invoke sbt with the "shell"
command. sbt has a mechanism for handling this in its "boot" command
that adds an "iflast shell" to the commands. Handle this when displaying
the "Executing in batch mode" warning.
Fixes#3004
Notify & enable users to stay in sbt's shell on the warm JVM by hitting
[ENTER] while sbt is running.
Looks like this; first I run 'sbt about', then I hit [ENTER]:
$ sbt about
[info] !!! Executing in batch mode !!! For better performance, hit [ENTER] to remain in the sbt shell

Fixes#2987
Before this commit, using dotty in your sbt project required to add:
scalaCompilerBridgeSource := ("ch.epfl.lamp" % "dotty-sbt-bridge" %
scalaVersion.value % "component").sources()
in your build.sbt. We might as well automatically do this, this reduces
the boilerplate for using dotty in your project to:
scalaOrganization := "ch.epfl.lamp"
scalaVersion := "0.1.1-SNAPSHOT"
scalaBinaryVersion := "2.11" // dotty itself is only published as a
// 2.11 artefact currently
SbtScalariform is now an AutoPlugin, so its scalariformSettings are
already added to the project. So don't add it again otherwise
`disablePlugins(SbtScalariform)` won't work.
And miscellaneous cleanups.
