README typo fixes
splatalogue bugfix: had configitems misconfigured!!
Switch to using ez_setup.py, and simplify setup.py, following recent changes in Astropy core.
Updates to __init__.py to match Astropy core
Minor fix
Added backward compatibility with Astropy 0.2
parallel option can only be used with Astropy 0.3 or later
fixed broked gallery example
Re-organize the setup.py so that Astropy is not required for egg_info
fixed an issue with a Vizier test: a warning was being read as an
exception by capsys, instead of "screen output", so I used recwarn
instead.  This error was never introduced: it has been there since the
first(ish) commit of Vizier, and therefore the astroquery "bug" has
resulted from an external change (perhaps to astropy?)
