Should use current_user_can for [12908], users.php Add New button

[nacin]

[12908] can be reverted as we already perform that check in map_meta_cap.

Additionally, we should convert that logic in users.php over to create_users.

I'll check this up again later.. if its in map_meta_cap its not working as intended

[dd32]

You're right. It is there, and it does work as intended.

The problem is that has_cap() returns true for ALL caps for super users, regardless.. and the file hasnt been updated to rely on the cap.

(In [12916]) Revert [12908]. Update Users cap to use a capability. See #12098. Props nacin
