WooCommerce 3.0 Compatibility

[scottnelle]

WooCommerce 3.0 includes changes which render Custom Related Products 1.2 incompatible. The following issues must be addressed:

• WooCommerce 3.0 introduces the filter woocommerce_product_related_posts_force_display and if that isn't true, no related products will show if there are no categories or tags set.
• WooCommerce 3.0 alters the means by which parameters are set when related posts are queried. Identify and resolve this issue.
• WooCommerce 3.0 seems to have once again changed the markup and/or underlying functionality utilized for asynchronous product lookups. Implement their new system (without breaking backward compatibility.) It may be worth implementing our own product autocomplete to prevent future breaks.
• Test thoroughly against WooCommerce 2.6 to avoid breaking changes.

Additionally, issue #7 has been opened and seems to indicate a javascript conflict between Custom Related Products, WooCommerce 3.0, and possibly Yoast SEO. I've been unable to replicate the issue as reported, but it warrants additional investigation.
