DATAMONGO-519 - Make Spring 3.1.2.RELEASE default Spring dependency version.

We move away from Maven version ranges as they complicate the build and dependency resolution process. They make the build in-reproducible. Users stuck with a 3.0.x version of Spring will now have to manually declare Spring dependencies in their needed 3.0.x version. Not that at least Spring 3.0.7 is required currently.
