Add options to record jets/MET to ESD/AOD in new config

The ComponentAccumulator-based jet and MET reconstruction config currently does not record the collections it creates to output files (ESD and AOD; the derivation framework handles output streams differently). For AOD is the behavior we normally want, but it's also helpful to have an option to turn on the recording of these collections for testing/validation purposes, and this functionality exists in the old config.

This enables the recording of standard Jet and MET collections to ESD by default, and adds flags to let the user also record them to AOD: Jet.WriteToAOD and MET.WriteToAOD, which are members of the central ConfigFlags object. These are False by default, but can be turned on by any user who wants these collections in their AOD.

Potentially of interest to @elmsheus, @williams, @sawyer, @schaarsc, @delsart, @khoo, @emoyse, @mswiatlo, @camacho.
