AntiSpoof

Bug fixes and stuff

Channels show first in the /antispoof check command to make it less confusing and spammy.

Fixed a bug where the alert shows a duplicated [AntiSpoof] instead of just one, this was because the alert section in the config included [AntiSpoof] but bukkit added it automatically as a prefix because it is the name of the plugin, so I just made a separate customizable console-alert option in the config that does not include [AntiSpoof] since that causes the duplicate.
