Local (untested) whitelist version attached. It hasn't been tested and it was written within five minutes, so do yell at me if it doesn't work and I'll repair it after I get off of work. Created on v0.1.9 of the plugin. All the plugin does is check the local KV and if the Steam exists, it returns before any code gets executed.

• smacbans-whitelist.ini goes within /sourcemod/configs/

Modifications for future versions.
