continuing attempts to fix vizier
finally finished fixing those damned vizier test failures.  The problem
was twofold: string issues (bleh) and dictionaries being unordered
(double bleh).  OrderedDicts are so ugly, but so necessary for this

hack hack hack to hack away the py3 bugs!
astropy versions are python-version-dependent.
SIMBAD passes both py2 and py3
there is a problem with the monkeypatch scheme - it will most likely
fail for astropy v<0.3, py3.  Who cares?
py2 besancon fix
besancon works with py2 and 3 now.  I hate unicode for this.
bugfixes to sdss for py3
SHA test fixes ('rb')
failed UKIDSS HTML parser.  py3 doesn't behave at all like py2, and

understand.
so close... so damned close.  Why the hell does vo.parse "expect" bytes?
It's a string object....
