chore: clean up inter-project dependencies (#1247)

Remove unused dependencies between the specs2 modules. This change is "breaking" in the sense that projects using the specs2 library may have to be more explicit with their specs2 dependency declarations; most notably `specs2-core`, `specs2-analysis` and `specs2-matcher-extra` may need to be added explicitly if e.g. only `specs2-html`, `specs2-gwt` or `specs2-mock` were depended on before.
