Add settings form to content types

[ghost]

When creating a node, you can define SEO meta tags for it. One of the options in the Open Graph section is the Type (website, article, product, profile). It would be nice to be able to set a default value for this on the content type settings form (e.g. set the default value of this field to 'Article' for the 'Post' content type), along with the ability to choose default values for the other fields (e.g. the Page Title tag gets its value from the node title, rather than having to type things twice).

Ok, just noticed that the Page Title tag is automatically populated from the node title 😄

Initial motivation for creating this module - to be simple as possible, not just copy another overloaded (IMO) module.
