CRAFTBOOK-3014 - Reported by Hammer.Head

I get strange error related to a "token" when starting craftbook (#3844-ba6c3f6). I get the following two errors, one when craftbukkit first starts, and the second when I try to save an area:

You've used a tab somewhere in the config file, or mechanisms config file. The YAML format doesn't support tabs, make sure to remove the tab from the file and then it'll work.
