A Golf Handicap: Record played golf games in a MySQL database

Version 1.1.0 of AGolfHandicap class

 1. Every field must now have an entry in the game input form.
    If one or more does not, it comes back to let you complete the form.

 2. Each record displayed in the games played table now has a Delete button 
    which enables you to delete that record from the database.

 3. Each record displayed in the games played table now has an Edit button
    Which enables you to edit or correct data in that record from the database.
 4. Added a Cancel button in the form to enter or edit games.
 5  To correct a sorting bug by date, the dates are now saved in the database 
    in the following format, mm/dd/yyyy. (with leading zeros and 4 digit year.)

    This means that if you have games entered from the original version of this
    class, for each game entered, you should click on Edit and then click on
    Submit to save the dates in the proper format. Otherwise the games will
    not sort properly and the handicap will not be calculated correctly.
