Add initialization logging configuration customization (refs #7).

Before user logging configuration can be loaded, pymin already can emit a
lot of logging information. This patch provides a way to customize the
logging configuration before the standard configuration framework take
place.

By default, it tries to read /etc/pymind/log.init.ini configuration file,
unless PYMIND_LOGINITCONF environment variable is set, in which case the
file specified by that variable it readed. If it fails to load the
configuration file, it use a reasonble default.

This is mostly useful for debugging/development purposes.
