Adding OT t0 time to protoparticle extrainfo

Split off from 2018-patches this weekend. This is effort by Manuel and Jacco 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. Reconfigured TupleToolTrackTime to make use of tool. Added an additional track fit option that uses OT hits only (Manuel). Added track T0 information to protoparticle extrainfo.
