SDSS fixed - just needed another function in __all__
StringIO -> BytesIO in ukidss
added two more needed functions to __all__
removed python3.3 tests: astroquery is NOT python-3 compatible at the
moment, but I want travis tests to be useful.
remove -w -n from build sphinx: for now, ignore warnings in the docs.
We'll need to change this by release time, but again, I want travis to
pass.
{} -> {1} for python2.6 compatibility
LAMDA fix: removed unnecessary overhead of conversion to numpy array,
and removed np.in1d.  np.in1d returned inconsistent results in numpy <
1.7 and numpy 1.7, and I couldn't figure out what caused the
inconsistency.
