Make "change mod settings" permission into 2

[unhott]

TL;DR

Make a "Change map mod settings" and "Change per player mod settings" separate priileges.

What ?

As TL;DR states.
If we wanted to go crazier it would be nice if you could identify specific settings that can be modified.

Why ?

I think this is important because server admins may want to prevent a random player from making a mod settings update that affects all players, but there is likely no reason to restrict them from updating per player mod settings.

You have to be an admin to change not-your-per-player-mod-settings anyway so I don't see the point.
