Allow templates to override the list of actions in the Extensions page.
Review Request #6071 — Created July 7, 2014 and submitted — Latest diff uploaded
The Extensions page now includes a new 'extension_list_actions' block
that can be overridden to provide actions. By default, it includes the
"Scan for extensions" action. Templates extending this should retain the
parent block's content and then add to it.
Extended the template and added new content to this block.
