Add ability to add more items to a table's order.  Within Orders tab,
clicking the "Add to Order" button will pass the current Order object to
the correct menu, where it will be interpreted and entered in the DB as
an 'addition' and added to the current Order object.  Once the Kitchen
staff completes the addition, it is removed from the DB since the
current order has already been updated with its details.

Integration Instructions:
- Add new Orders "Status" datatype called 'addition'. This will make a
total of 5 datatypes (entered, addition, served, paid, split).
