Improved Eclipse support for the Bazel project
Now the paths are 100% determined using Bazel query. To adapt to
another project, change the variables at the top of the
setup-eclipse.sh file. It also handles correctly java_plugins now.
Because we must do queries on the full workspace, it is not easy to
embed in a bazel build. I made a prototype for it but it is really
impractical.
