Added functionality for quarry limiting

Hi there,

Found your addition to worldguard with a bit of help from a user on my server. We are currently running FTB Unhinged and I was wondering if you would be able to update your plugin to 1.5.2, and change the quarry ID to 1503 for us. 

Many thanks for taking the time to read. Great job with your previous version, and good luck in the future if I don't hear from you :)
