Eclipses and Minor Holidays

Added lunar eclipses and solar eclipses at a low random chance each year.  I also revised the full moon so it takes 29 days (more or less) as normal. Also, apparently a Jewish friend of mine said they always experienced the full moon on the same night of the month, so I made two lunar phase "calendars". Then I worked on holidays, especially April Fools Day.

Still haven't done the lunar holidays, but all regular holidays are done with.
