Zodiac cleanup

I've finally cleaned up the zodiac entries from the older calendars in the DB.  Early in the project zodiac indications, such as "Sol in gemini", were included along with the saints in the main listing.  Later on it was decided to only put these in the Notes, trying to mix them in with the saints got too complex and often caused "three saints, one day" issues.  Newer books were done this way, but it was not until today that the older entries were cleaned up and standardized.
