core (log): configuration and environment variables are now checked for log level and colors: - variable change logs behaviour, so far only level and colors are implemented - configuration use log_[name], for example you can put log_level=debug in sat.conf (section [DEFAULT]) to see all levels - environment variables use SAT_LOG_[NAME]: e.g. SAT_LOG_LEVEL=debug - colors can be true, false or force to force colors even if stdout is not a tty
