Add a connector from Sixbit to shopify

Our ebay listings are submitted using a product called SixBit -the full API info is available here: https://www.sixbitsoftware.com/docs/SixBitAPI/webframe.html. As soon as something sells on eBay the SixBit listing is automatically modified (available quantity, etc). We also have an ecommerce site powered by shopify. We want the same functionality between SixBit and Shopify that we already have between SixBit and eBay/Amazon.
