Added deleteMenuItem plus some constants.
Changed getMenuItemById to use getRecordById();
Made changes to better use the database.  Especially getting the list of menu items that was selected.
Cleaned up OrderController.java and displayTotals.jsp so the .jsp could use EL expressions for output.
Changed AdminController to work with administration.jsp page.
administration.jsp creates a table of all menu items.  Will be adding buttons for changes and deletes.
