[FIX] sales analisis 6.1 version

[Ariel E. Figueroa - http://www.humanytek.com]

hi team, please see this case:

this customer use one cutomized module sfs_price_multicurrency_qb to the users can set the currency f the price on the product.product model.

now the main problem on this bug is the sale analisis view located in SALES / SALES / REPORTING / SALES ANALISIS

dont calculate correctly the amount of the column "TOTAL PRICE"

case 1:
if users sale the product using MXN pricelist selling
[0000016] QUIMICA BOSS DEMO PRODUCT 1 MXN CURRENCY PRICE
the column "TOTAL PRICE" show the value = 5 this is correct because MXN are the base company currency

case 2:
if users sale the product using USD pricelist selling
[0000015] QUIMICA BOSS DEMO PRODUCT 1 USD CURRENCY PRICE

the column "TOTAL PRICE" show the value = 5 this is wrong because the report are making a sum of 5 MXN + 5 USD = 10

All the prices set in different currency to as base company currency ( MXN in this case) must be converted in the report calculating the correct rate of the currency taking the date of rate from currency.

Thanks!
