BeachComber - fast and efficient beach combing

[Veracity]

Revision #46 updates BeachComberFix to strip out all logPreferenceChanges logging before processing a log. Thanks, Rinn!
It also removes all vestiges of the original use of this script - extract tile types from logs - which is now obsolete, since spading of such is complete.

BeachCombing depends on tides, which come in and go out over an 8 day cycle.
We used to depend on the _beachTides property, but we can simply derive them from daycount().

Revision 47 does that and provides a couple of friendly commands:

> BeachComber tides

The tides came in today and 3 rows of the beach are now washed by waves.

and

> BeachComberUtilities tides
