Added spectro keyword in sdss.core to break the requirement that a match be both photometric *and* spectroscopic.
Changed default value of spectro keyword argument to False, i.e., look for photometric matches only by default.
Merged with upstream master.
Added spectro=True to sdss/tests/test_sdss/test_sdss_spectrum.py, add note about new spectro kwarg to docs.
Merge remote-tracking branch 'upstream/master'
