Configurable logging

I have just committed updates to the "linelog" module (including documentation) that significantly increase it's usability. The goal is to move most of the hard-coded log messages to this module. Once these log messages are added to the configuration, the existing hard-coded messages can be deleted. We're looking for volunteers to examine the existing log messages, and to submit sample one-line log formats for the "linelog" module. Alan DeKok.
