Title: [Scala] release candidate 2.10.2-RC1 for --devel

There are actually two development versions available. One is this RC, bumping the patch version from 2.10.1 to 2.10.2. There is also a milestone release for the next minor version, 2.11.0-M2. I'd say, --devel should install the next version that is closest to the current stable version.
