CPAlgorithms: allow for event selection at particle-level

Some users need to run the event selection algorithms using so-called "particle-level" objects (TruthElectrons, TruthMuons, etc.). This requires the following changes to the event selectors:

• make the MET term a configurable option: at reco-level it's most likely "Final" (new default), at truth-level it's most likely "NonInt"
• replace xAOD::ElectronContainer etc. by xAOD::IParticleContainer to be able to pass either reco- or truth-level containers
• in a couple of cases, event selectors need to access charge(), which is not available for xAOD::IParticle. There I simply added dedicated xAOD::TruthParticleContainer handles, and I populate the correct type of handle based on a switch in the python config.

this looks good to me from AR side, but given the amount of analysis code involved, I'd ask @krumnack to also please have a look

@krumnack - do you want to comment on this?

Ah, sorry, lots going on in the last week.

While there may be easier ways to do the same thing, this does the job and is not directly user facing, so I think this can go in.

Regards, Nils
