Issue: vw-list-contributors should inherit style properties from class usertitle and DateTime

vw-list-contributors already uses the class "username", which is the only consistent class for usernames that I see in the default XenForo style, so long as the contributor was not a guest. I am not sure how XenForo handles styling for guest posts; I will have to look into that and make sure the behavior is consistent.

Since vw-list-contributors uses XenForo's datetime template helper, I am actually surprised that it does not automatically add the DateTime CSS class. I will review whether another argument is needed when calling the helper, or if it is necessary for it to be included elsewhere in the template.

Please see my live site. The class username on forum index has font size 12px.
Yet, vw-list-contributors has 14px on the wiki index. If it inherits then its getting overruled.

If you are referring to your forum index's sidebar, those usernames have a very specific .sidebar .username class which would not apply to .vw-list-contributors because it is not in the sidebar.

The usernames in the main forum list (last post column) are inheriting the font size defined for the .nodeLastPost column, which is not relevant to .vw-list-contributors, but only to container-like node-list entries, like a list of forums or list of wiki areas. It is not defined for the .username class itself. If you set a font-size for the .username class specifically, then it will be applied everywhere the .username class is used (including .vw-list-contributors), unless it is overridden by something more specific like .sidebar .username.

Then how should VW inherit the correct styling for .vw-list-contributors so that it complies with XF styling?
All such bylines are small, muted. These are not individually defined but use XenForo style properties and color palette properties. In this case @mutedTextColor
/admin.php?styles/master-style.0/style-properties&group=color

A new style property has been created for the next release which applies to the entire contributor area: Wiki Pages > Below Content. The default value for this is a smaller font-size than the default value for Main Content. You can also change the font color here if you wish.

Additionally, the DateTime class has been added to the created/updated elements.
