Price file importing tweaks

• Bugfix with importing discount code, would not record discount code for new records but would record it for subsequent changes to existing records
• Bugfix with detecting changes on certain fields due to nulls in database, i.e. discount codes.
• Import generic : permit importing discount code from generic but not nag user to key in % if the csv file already contains independent info on stock/discount $/%
• Import from c9 repository : also import packqty/ order by pack flag and metadata if available
