CPAlgorithms: an easier way to disable global trigger matching and efficiency

Introduce an option noGlobalTriggerEff to skip setting up the global trigger efficiency tool (including matching), which crucially does not run on Jet/MET triggers. This should make life easier for such users, who otherwise have to pass their triggers as a list under triggerChainsForSelection, instead of the (nicer) dictionary triggerChainsPerYear.

I'm also removing the make-method for trigger configuration, as it's becoming deprecated.
