* Got Log->entry() working now. Decided to use journald logging exclusively... They've thought a lot more about logging than we will, and the idea that there are special facilities for sensitive log entries and the ability to perform remote logging was too appealing.
* Created Log->level() to set/check the currently active log level.
* Created Log->secure() to set/check whether sensitive log entries will be recorded.
