Templated additional b taggers

[ferencek]

This PR templates track counting, jet probability, and simple secondary vertex taggers and adds their candidate-based instances. New taggers are also propagated to PAT.

The changes should be completely transparent to Reco as can be seen in the following three plots produced by running over 1k ttbar events:

TCHE

JP

SSVHE

For reference, also adding performance plots for the candidate-based taggers:

pfTCHE

pfJP

pfSSVHE

Tested with CMSSW_7_3_X_2014-11-14-0200.
Only additions of new algos at AT level, which run fine in PhysicsTools/PatAlgos/test(patTuple_addBTagging_cfg.py

The standard RECO outputs are unchanged.
This includes no changes in the pfImpactParameterTagInfos and pfSecondaryVertexTagInfos candidate-based taggers running in RECO.
