Changed _create_move_line to modify location names during location matching.
Fixed error in vmi.vmi_stock_picking_in.action_flag_audit (res.extend instead of res.append)
Added vmi.vmi_portal.get_vendor_by_name
Modified vmi.vmi_portal.VmiController._create_move_line to use _default_stock_location_suffix for validating location field in CSV file to stock.location names.
Modified vmi.vmi_portal.VmiController._create_stock_picking to lookup partner with supplier name from CSV value
to allow for adding packing slips for multiple suppliers within the the same CSV file.
Cleaned up some messy code.
