Permission Fix

I really need you to lookover my pull request again:

If you notice, there is a big difference with the parentheses. Through multiple testing, I've found that your lack of parentheses have caused this bug:

For Example if perm = "libsdisguises.disguise.ocelot.option"

perm.split("//,")[0].equals() is checking -> "libsdisguises.disguise.ocelot.option"
(perm.split("//,")[0]).equals() is checking -> "disguise"

I hope you reconsider, this is a pretty bad bug because it makes the new permissions feature unusable in many cases.
