Replace SDSS query and templates URLs
Fix bug with `names` and first comment line

When using np.genfromtxt with names=True, the first comment line is examined
for names
http://docs.scipy.org/doc/numpy/user/basics.io.genfromtxt.html#the-comments-argument
and the first line of the SDSS returned data is a comment but does not contain
the names, which are on the second line.
