Adding logging conf file to allow sending mail and adding handler
without modifying the program file. It is possible to configure
the level when the handler will log. I also modified the log level
of some command/functions. The goal is to delete the write.stderr
to replace it by the logger function which will display on screen
and on other handler. With this behavior it will be possible to
report incident like kicking and some other troubles by mail or
other handler.
