ConfigObj as an alternative to configuration parsing

[whart222]

I needed for my app more robust support for *.ini files parsing. (especially UTF8 encoding in ini files)

I was not sure how to create a new config parser plugin so I've just modified module pyutilib.component.config.plugin_ConfigParser' to use configobj instead of ConfigParser.

That modification works for me. However, it will be necessary to create a proper configuration parser plugin, to be able to choose between ConfigParser and ConfigObj parsers.

Attached is the modified file plugin_ConfigParser.py in order to use configobj instead of ConfigParser.
