Adding OT t0 time to protoparticle extrainfo

Split off from 2018-patches this weekend. This is effort by @mschille and @jadevrie to put the OT Track Time into the protoparticle extrainfo, for potential use in e.g. ProbNN. We want to see how the nightlies manage this, so it can be included before the restripping.

Details: Created tools for OT Track time information. Hence, the tupletool can make use of that now.
