   the locale setting unless configured otherwise
 - New configuration file settings:
   ShowRate, RateUnit, TrafficlessDays, HourlyRate, TransparentBg

 - Fix: Updating a database from two of more processes at the same time
   was able to sometimes cause data loss
 - Fix: Estimates are calculated based on last database update
 - Fix: Each interface update had a possibility of losing 1023 bytes of
   traffic at most due to improper rounding
   (Thanks to Michael Berlin for suggesting a suitable correction)
