v0.1

This is the first release of my little script.
It is still in testing. The following things have been changed compared to the last version:

• Additional config-value in config.ini
  DEFAULT->SignOfLifeLog
  Sets the time in minutes a log-entry is written with latest status (last-update time and last ac-power value)
• Fix bug in _update() that leads to remove of 'timer'-call, which means that the script was doing nothing :-/
