Revision 1861861

Applied fix from trunk for revision: 1861859 
===

Fixed: Issue in which Ecommerce anonymous contactus was having wrong fromAddress.
(OFBIZ-10844)
As per my understanding, sendFrom email cannot be the customer's email address.

Email settings for this email are maintained at ProductStoreEmailSetting with CONT_NOTI_EMAIL as emailType and like other notifications, we should use ProductStoreEmailSetting.fromAddress to send this email which is configurable.
Thanks: Schumann Ye for your contribution.
