kallithea_config: properly handle Unicode characters in .ini template

The kallithea_config.py script did not allow Unicode characters in the
configuration file template template.ini.mako. Following error would be
given:
    Traceback (most recent call last):
      File 
"/home/tdescham/repo/contrib/kallithea-fixes/kallithea/bin/kallithea_config.py",
 line 141, in _run
        f.write(tmpl)
    UnicodeEncodeError: 'ascii' codec can't encode character u'\u2002' in 
position 2087: ordinal not in range(128)

Instead of using plain open, use codecs.open, as per the Unicode HOWTO:
https://docs.python.org/2/howto/unicode.html#reading-and-writing-unicode-data
