entity:acfLinkToAmmoBox and entity:acfUnlinkFromAmmoBox

I'm sorry, I'm not used to github. I don't know how to edit multiple files but my suggestion is to add these two functions, they're tested on Social Players server.
The function description code:
```
E2Helper.Descriptions["acfLinkToAmmoBox"] = "Links ACF weapon to ammo box. If notify is higher than zero, a notification will be sent when the weapon has been linked. Returns 1 if it linked successfully, otherwise returns 0."
E2Helper.Descriptions["acfUnlinkFromAmmoBox"] = "Unlinks ACF weapon from ammo box. If notify is higher than zero, a notification will be sent when the weapon has been unlinked. Returns 1 if it was unlinked successfully, otherwise returns 0"
```
