Bug 582078- Cannot install via Oomph due to EclEmma update site

This commit solves the existing problems while installing via Oomph:

- The Mylyn EGit connector feature has been renamed and the Mylyn
repository URL has been updated.
- The EclEmma repository URL has been updated.
- FindBugs has been replaced with SpotBugs, as the former is not Java9+
compatible.
