setup: requires requests [resolves issue #237]
Merge branch 'master' of github.com:astropy/astroquery
added test/__init__
added tests that were hidden and made them pass
attempt to both fix doctests *and* skip them.  The fix worked as far as
it was supposed to, but doctests will still fail because they attempt to
make outgoing connections where they should not.  The __doctest_skip__
failed.
