v490.9 dev1 - improve selection of images on mscw stage; bug fix in event selection for dispAnalyzer

[GernotMaier]

NOTE: wrong branch name, this is v490.9

This pull requests introduces changes related to the selection of images for the stereo reconstruction on the mscw_energy stage. Goal is to allow a looser image selection for the stereo reconstruction on the mscw_energy stage compared to evndisp:

• in evndisp, images are selected according to the settings in the reconstruction parameter file (e.g., see here)
• in mscw_energy, images can be removed from the stereo reconstruction by e.g., a --maxloss=0.2 command line parameter.
• image selection and number of images in reconstructed are now correctly updated after redoing the stereo reconstruction with disp

This pull request allows now that mscw_energy uses looser cuts. For this, add the command line parameter -use_evndisp_selected_images=0.

Additional changes:

• bug fix in setting quality cuts for angular disp analysed (fui was not set correctly; this does not have any impact unless one uses very loose (>0.9) loss cuts
• simplified settings of quality cuts (including loss) for trainTMVAforAngularReconstruction
