Add a temporary script to create docstrings (help for issue #82)
sphinx-quickstart
Add __repr__ to _NotSetType

We don't want "<github.GithubObject._NotSetType instance at 0x00000000037B1A48>"
in our generated documentation.
First draft of generated documentation (issue #82)

1) ./generateDocstrings.py
2) cd doc
3) make html
4) open doc/build/html/index.html
Improve generated docstrings (slightly)
Remove unused file
Use absolute imports. May help with Python 3
Small fixes => tests pass after 2to3
Restore Python 2.5 and 2.6
Enable Python 3 in Travis
Fixes for Python 3: setup.py install will call 2to3

Restore Python 2.5 and 2.6
Add Python 3.1
Restore Python 2.5
pep8 + readme
Reference issue #93
