Fix setup.py so that bdist_wininst works.

Leaving the maintainer's name as a string (as opposed to a unicode)
was triggering a UnicodeDecodeError when running bdist_wininst with
Python 2.7.3
setup: Emacs actually don't like UTF-8, prefers utf-8
setup: using u'...' breaks for Python 3.[0-2].
Merge remote-tracking branch 'cboos/bdist_wininst'
Cosmetic fix to setup.py
