Add initial archive view for University Center object types

Removes the sidebar from the default archive templates when displaying
University Center objects
Duplicate the default post article view to the project object type
Pass post type rather than post format to the post.php template
Remove commented out, unused code from single template
Add default single layouts for University Center objects
Use a post type for the single and archive layouts, not 'standard'

This will allow child themes to override the default single and
archive `<main>` layouts for any post type
Add default article layouts for entities, peope, and publications
Always show the title for people
Never show the date and author for people
The University Center people post type is "person", not "people"
Remove other unused parts of a person layout
Move the thumbnail for the person before the title and style
Remove unnecessary taxonomy display for people
Individual people, projects, entities, publications should be single layout
Handle the floating of data automatically inserted by the plugin

This may be smart to change later
Remove large amounts of unused code for new layouts
Date and author does not yet matter in this context

It will, likely, but not in this way.
Always show the title on entities, projects, and publications
Only show manual excerpt if available for entity, project, publication
Remove unused get_comments()
