Redundant + too many + badly structured messages in log

Log messages should be cleared for pure debug messages and redundant messages
prior to releasetesting.
Log may benefit from structuring e.g. indicating the name of the process and
overall function that is being performed.
Consider delimiters (e.g. dashed line) between logical sections.
