Bookkeeping module

[stagebrace]

Update

• Forces SSL if its set to be used in configure.php
• Added "@" to all mysql functions. (don't understand what it does, but it fixed no connect issues)
• Makes the bookkeeping table `bk_expenses` if it has not been made already. (No SQL to upload by the user. The table may change soon to accept encrypted data)
• Shows some customer data for an order number.
• Saves order number as cookie (its the safest way to pass a JavaScript variable to a PHP variable)
• Log in to Zen Cart, admin>tools>Bookkeeping
• Re add display for product sold for an order number
• Re add form for expense per order (with add a row button)
• Expense form multiplies the quantity and price then copies it to total.
