[gh-388] Provide ability to edit Page Title and Meta Description
From the WDN wiki 'Best Practices' section:
Title (encoded) The page title as encoded in the <title> tag should read as follows: Page Title | [ Site Title |] University of Nebraska–Lincoln. In general, the Site Title can be omitted unless necessary for context.
A content editor (or other appropriate role) should have the ability to customize the title
region to remove the Site Title, and/or to enhance the page title as necessary.
For SEO purposes, there are varying degrees of need. While the default should be the WDN best practice, it would be helpful to allow changes.
