#25425: Last separator in network and user menus not removed

 Priority:  normal           |  Milestone:  Awaiting Review

 Severity:  normal           |   Keywords:  has-patch
-----------------------------+-----------------------------
 In `/wp-admin/network/` and `/wp-admin/user/` the last separator is not
 trimmed off.

 This is caused by the ID of those separators being `wp-menu-separator-
 last` and not `wp-menu-separator`

 Screen shots attached to outline the problem.

 * First patch renames the final separators, since `wp-menu-separator-last`
 is not referenced anywhere else in WordPress core.
 * Second patch keeps the ID's the same (for backpat with who-knows-what)
 and tweaks the code that removes the final separator in `/wp-
 admin/includes/menu.php` instead.
 * Bonus patch to adjust a separator capability from `read` to `exist` to
 match the other two.
