Refactored for connectdialog.py and maneframe.py
Have fixed the problem with added buyers not showing up when I want to print a cart or receipt.  I did it by having ManeToolbook reach way down into PrintBuyerCartOrReceiptForm and invoke the BuildChooser method.  There are lots of print statements that I want to remove before committing to github, but I want to commit these changes before starting to delete lines.
