logging: color the log category according to level
When log_set_use_color() is enabled, color the log category string according to the log level. The log line before and after the log category is printed in the category's configured color. ERROR and FATAL are red, NOTICE is yellow, INFO is green and DEBUG is blue. The default behavior remains unchanged; If color is enabled, the category string will now always be colored in the log level color, not the log category color, and will stand out from the rest of the line.
