Show Blog entries on a product-detail page that are related to the specific product

[ChristopherDosin]

The idea is to show also blog entires on a product-detail page that belongs to a product for version 2.0 Maybe you want to write an article about a specific product.

Therefore we should create a new CMS Block & Element so the user is able to place a blog-product element to the product-detail page where we will show the blog teaser that are related to a product.

Within the administration we need to add a new multi-entity-select so the user is able to attach a blog article to a product also. This assignment option should be optional.
