feat(settings): TACC_BLOG_SHOW_ABSTRACT_TAG

[wesleyboar]

Overview

If tag matches setting value, article page will show the abstract.

Use Cases

Actual: So that if a user navigates to a page that they were not intended to access, the abstract can be shown to show them to where they should have been redirected. (That redirection relied on abstract having a link to an external article, but relies on JavaScript which can fail. Also, user could have pieced together the URL or received it in full via RSS.)

Imagined: Scientific article whose abstract should be listed before the content so all content is available together.
