Report all missing Scala dependencies

[gkossakowski]

At the moment dbuild will report just one missing Scala dependency that is not already added to the config file. It means one need to rerun dbuild for each missing dependency. Given that each dbuild invocation is quite slow, the experience of somebody adding a new project to dbuild configuration is not that great.

Possible workaround: fire up consoleProject and list all Scala dependencies. My sbt-foo is not good enough to offer a code snippet to run, though.

yeah, this is a pain point

not so painful anymore now that the 2.12 build is largely frozen and the 2.13 build was restructured
