JetAccessories: avoid cloning and double ownership (and thus double delete) of Particles
- address this bug: f9a17847 (comment 7784341)
- use Particle::Selection instead of Particle::Container where appropriate to avoid cloning Particles
- avoid cloning of Particles in makeFastJets
- use Particle::Range instead of Particle::Container const& where appropriate
- use 'lazy' (on demand) range to obtain 'basic' particles from a composite
