Include provided dependency in runtime classpath

[tgodzik]

Currently, when exporting Bloop configuration files from sbt, the provided dependencies will be on compile classpath, but not on runtime classpath. This is inconvenient for local debugging, since we will run without jars needed by the application.

This actually is valid behaviour since -> A dependency with this scope is added to the classpath used for compilation and test, but not the runtime classpath, but is very inconvenient for users.

I would opt to include provided deps anyways in the runtime classpath, but I wasn't able to figure it out.
