Add version 0.30 of OleFileIO (2014-02-04)

New release from Philippe Lagadec, http://www.decalage.info/python/olefileio

I also added some simple tests, and some `assert_greater()` etc. tests to tester.py.

Brings overall coverage from 65% to 69%, and coverage for OleFileIO.py itself from 15% to 63%.

I'll contribute the test back to Philippe, as well as run.py and tester.py so it can be run.
