Update CondFormats

[JoramBerger]

The test script currently uses the CondFormats version in Georg's web space. This differs from what you get with git cms-addpkg CondFormats/JetMETObjects. The only difference should be that we remove dependencies on CMSSW logging and error handling. The code should otherwise be the same. Currently, there are more than 100 lines different. We do not need parts of the code that care about serialization into ROOT files as we only handle four-vectors of jets within our programs.

A recent CMSSW version should be chosen and the removal of CMS dependencies should be done via a script (sed) to automate the updating in future.
