NEW-Add a late fee to invoice

NEW FEATURE for Pro users.

After creating the invoice, you can click Enter Payment on the invoice. Toward the bottom, you will now see a section that says "Add Late Fee". Type in the percentage for the late charge (example: 3 for 3%) then click "Set Late Fee". This will automatically add 3% to the total fee. When you print the invoice or send it via email, you will see the late charge and a red "past due" notice in the top left corner. (see picture below)
