function _ip_ban_set_ban_value in IP Ban 7

Function sets user's ban value (if any).

Load the user's country code based on their IP address, then check if that country is set to complete ban, read-only, or has no access restrictions. We then do the same for any additional read-only or complete ban IP addresses added. If the user matched a country or an IP address entered, then they are shown a message and/or redirected based on complete ban or read-only.
