[Pixelmon] Permissions cleanup

[Dpa1991]

I've reorganized the Permissions file a bit and tried to reduce redundant inheritances and permission nodes. During the cleanup I removed all individual legendary ranks and created a single Legendary Rank and changed everyones individual prefix to match their previous rank.

Prior to this cleanup, the permissions file had 34,796 lines after the cleanup it has 25,796 so this was pretty extensive. If you notice anything strange post here and I'll try to fix it.

  If your rank is not correct, you can set it here: Click just enter your username and select the rank you had or post in this thread if you cant figure it out.
