Remove permalink from titles

The permlink is already available with the "Share" action: the behavior of the permlink in the 5.7.3 is in fact an action and the real action behind is "Open in a new tab".

• The action should be displayed on the right side with the other actions (download / share / etc)
• The label and icon should be updated
• A new template for the title should be displayed (with a relevant name) and should contain only the title.
• The title and permlink widget should be deprecated.
