changed simbad extractor to look at systems first by default (not kepler) - added try except for web lookup fail
added try except to stop simbad_extractor.py script failing in cases where there is not parent object (binary / star) i.e. floating planets
simbad_extractor quit on fail, changed comment style of spectral type system
updated magnitudes using simbad_extractory (pulls from simbad website)
