How can i get the plugin to use the material of the upgrade? Intead of saying "Automatic upgrading is now set to grade {0}", where {0} returns a 1, 2, 3, 4 I would like it so return Wood, Stone, Metal, HQM. I have seen other servers where this happens.

In the lang file, there is a line called "Words.Disabled". On the Main page of the plugin, it shows the lang file with these entries:

"Words.Grade.1": "Wood",
"Words.Grade.2": "Stone",
"Words.Grade.3": "Metal",
"Words.Grade.4": "HQM"

It seems this was intended, and I am sure somepeople have it working. I just want to know how!
