Sales report 2.0

[docfx]

changed this:
$product_tax = (zen_calculate_tax($onetime_charges, $tax)) +
(zen_calculate_tax(($final_price * $quantity), $tax));

to this:
$product_tax = (zen_calculate_tax(($final_price * $quantity), $tax));

Sorry, this is a blind alley... didn't fix the symptom after all. Problem still exists in PROD section of report, but not in the TIMELINE or ORDER sections of report. Turned on the "DISPLAY ONE-TIME FEES" category in the report and it shows 0 in fees.

<sigh>back to the drawing board</sigh>
