More reconstruction algorithms

The goal of this is to reproduce the Hlt2 dataflow as we have in Brunel. Most of it is defined here.

• New options file and test added: Hlt/RecoConf/options/hlt2_reco_brunelesque.py, Hlt/RecoConf/tests/qmtest/hlt2_reco_brunelesque.qmt
• Added algorithms (Hlt1): PrPixelTracking, PatPV3DFuture, PrForwardTracking, TrackEventFitter with the respective decoding, clustering and converting algorithms
• moved track fitting to hlt1_tracking
• TrackBestTrackCreator now takes fitted Hlt1 forward tracks
• splitted up helper functions for hlt1 and hlt2 forward tracks (all_hlt1_forward_track_types,all_hlt2_forward_track_types)
• renaming of some makers so that the algorithm name is part of its name
• "align" docstrings and comments thoughout RecoConf
