Tweaks and fixes

• Import part images
  • Import images + metadata for Fox Racing for website content.  Better, faster and more detailed dataset provided by Fox Racing, instead of using the b2b portal. Among other things it grabs a detailed part description and supports multiple images per part.
  • Tweak WPS to grab part list & description over encrypted channel. (Low risk issue but since I made newly added Fox use encryption might as well tidy up WPS)
• Bug fixes
  • Merge multiple pickups into one in point of sale. Base invoice would grab and apply original discounts, but the merged invoices by default would not have discount applied. Now fixed.
