Check the validation of the new product

[ryndel]

User testing comment "When creating an empty title product there's no “warning” that says that this feld was empty and it automatically creates an “object object” product name. I think you should better avoid this kind of empty felds or products and tell the user to fll those felds."

Fixed validation - now checks that currency and period have been selected, along with all other fields
