Fixes and tweaks

• Honda Order Export API : Make shipping config separate from shipping setting for OPEA based export. Because of reliability issues with DealerNet API dealers occasionally need to switch to OPEA method. Shipping setting here is different to setting for Export API. Making their storage separate will make process of switching export method a bit smoother.
• Bugfix with import PDF files for receive spares where some spares have packqty set.   The system recomputes qtys for packed items but it incorrectly can use pack settings from unrelated parts to influence other parts on the receival under some complex circumstances, causing their qtys to stuff up.  Now fixed in this version.
