set changelog date for v0.8.1 correct
little edge case of modules that don't have a scope_names_generator, which is unfortunately missing, but not really used in Jedi.
At europython's hackathon we played with it and @scoder added a small script to cython/Cython/Compiler/JediTyper.py, which makes it possible to add Cython types to a Python script.
Fixed whitespace problems in completion tests
Added tests for random.choice
Added pytest-cache to tox.ini

This allows you to only run the last failed tests using `py.test --lf`
or `tox -- --lf`.
Implemented support for namedtuples (fixes #107)

Note that namedtuples are only supported for Python >2.6.
