Build system broken

[uholzer]

There are two several problems:

urs@speedy:~/p/RDFLib/sparqlwrapper$ pip install --user .
Unpacking /home/urs/p/RDFLib/sparqlwrapper
  Running setup.py (path:/tmp/pip-0_cPU0-build/setup.py) egg_info for package from file:///home/urs/p/RDFLib/sparqlwrapper

There is a dot missing between SPARQLWrapper_ and __authors__.

Having fixed this, it works for Python 2, but running pip3 for Python 3 exposes another problem:

urs@speedy:~/p/RDFLib/sparqlwrapper$ pip3 install --user .
Unpacking /home/urs/p/RDFLib/sparqlwrapper
  Running setup.py (path:/tmp/pip-s1q1yjhc-build/setup.py) egg_info for package from file:///home/urs/p/RDFLib/sparqlwrapper

        import SPARQLWrapper
      File "/tmp/pip-s1q1yjhc-build/SPARQLWrapper/__init__.py", line 187, in <module>
        from Wrapper import SPARQLWrapper
    ImportError: No module named 'Wrapper'
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):

  File "/tmp/pip-s1q1yjhc-build/SPARQLWrapper/__init__.py", line 187, in <module>

    from Wrapper import SPARQLWrapper

It's probably a bad idea to import SPARQLWrapper before it has been tranformed by 2to3, because setup.py is also run by Python 3. (It seems this particular error occurs because relative imports in Python 3 don't work without a leading dot anymore.)

The current code at master (d635280a7b22fcddec7e38462c1405899ca8729e) should fix both issues. Please @uholzer test it, and fell free to re-open it if there is any missing details that should be addressed.

Thanks, this works.
