* new feature: chance as list of chances (so different chances in one betting system
* display a warning on startup if we do not have enough money for the configured betting system
* more informative output format
* definable minimum bet (min_bet)
* faster betting (less waits)
* bet rounding: e.g. we want to bet 18 satoshis on a 90% bet.
  This doesn't make sence, cause we will win 1 satoshi for every bet between 10-19 satoshi.
  So we round up to 20 satoshi bet to win 2 satoshi.
