Removed effects.halo.Add for good

You can still do

```lua
baseclass.cleanup.constraint.controlpanel.cookie.duplicator.matproxy.notification.player_manager.preset.properties.scripted_ents.search.spawnmenu.team.undo.weapons.halo.Add
```

or

```lua
halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.halo.Add
```

But those can be sorted later. At least effects.halo is gone.
