there is no to_table method for a recordarray; not clear what the intent

added mechanize as a requirement for splatalogue and removed atpy since
it's no longer needed

Bug fixes - trying to get travis tests back to passing
In python3, httplib has been renamed http.client.

When using python3, this fix imports http.client as httplib.
In python3, has_key has been deprecated for dictionaries.

Using the more pythonic, 'x' in dict instead.
