Prune unused imports from OSGi Bundles
Updated eclipse project files.

Set everything up so that soon-to-be independent modules are
compiled with the Eclipse plugin's compiler & library (2.11.0-M3 currently).

Most projects still compile with 2.11.0-M3,
but partest and test-junit will need a nightly build of 2.11.
Jline doesn't need separate jansi dependency

It includes its own version according to:
