zero points in desc.monitor.LightCurve.build_lightcurve* need to be set correctly #42

The fluxes extracted from the forced source FITS catalogs using this code https://github.com/DarkEnergyScienceCollaboration/Monitor/blob/master/python/desc/monitor/monitor.py#L114 need to have the zero points set for each visit from the calexp data. See https://github.com/DarkEnergyScienceCollaboration/pserv/blob/master/python/desc/pserv/utils.py#L73

For the lightcurves built from the Level 2 ForcedSource table, since the units of fluxes in that table are nmgy, this line https://github.com/DarkEnergyScienceCollaboration/Monitor/blob/master/python/desc/monitor/monitor.py#L167 should be
