Better Eclipse support

[jmakeig]

The project must not require Eclipse to build/run/test. However, there should be an easy way for a developer using Eclipse to easily set up her environment. This likely includes, but isn’t limited to, .project, .classpath, and perhaps, .settings/.

The resulting configuration should compile and build with zero warnings.

Should we require the m2e plugin? egit.

This is done for EA2, right? And @gghai verified it manually.
