Following up on my long standing threat to remove internal_link hook. Templates make it unnecessary, it is inefficient, and the only plugin using it requires a source patch to the same code anyway. git-svn-id: https://svn.code.sf.net/p/squirrelmail/code/trunk/squirrelmail@8397 7612ce4b-ef26-0410-bec9-ea0150e637f0
Reenabled the move_messages_button_action hook and changed its name to mailbox_display_button_action to promote the new location. This name change will also make it easier for plugins to support both stable and devel, instead of breaking alot of things git-svn-id: https://svn.code.sf.net/p/squirrelmail/code/trunk/squirrelmail@7931 7612ce4b-ef26-0410-bec9-ea0150e637f0
