Added a source bundle for the sbt library.

This commit allows debugging, hyperlinking, etc. towards
sbt sources. Useful when working on the Sbt builder.

* create a source bundle for the sbt library. I needed to
  inline the contents of sbt jars in order to get Eclipse
  to correctly associate sources with classfiles

* created a new compiler.interface bundle, only for the
  compiler interface, together with the matching
  `compiler.interface.sources` bundle. Sbt requires this to
  be a separate jar and there was no way to build a single sbt
  bundle with only some of the dependencies inlined.

A similar approach could be used for the Scala library/compiler
bundles, but we should investigate the possibility of having the
Scala team publish source bundles too (Re #1001889).

(this was originally a commit from @dragos, which I have adapted
based on the comments in #482)

Fixes #1001888
