Permissions

There are three "group" permission nodes, that give a bunch of nodes.
First, a list of those nodes. Then, parent nodes and lastly defining what every single node is.
I generally suggest you give yourself vanish.standard

vanish.standard:

  vanish.vanish
  vanish.list
  vanish.nopickup
  vanish.nofollow
  vanish.notrample
  vanish.nointeract
  vanish.nohunger
  vanish.fakeannounce
  vanish.preventdamage
  vanish.statusupdates
  vanish.adminalerts
  vanish.silentchests

vanish.op: The nodes that ops get
  vanish.reload
  vanish.adminalerts
  vanish.permtest.all
  vanish.see
  vanish.vanish
  vanish.statusupdates
  vanish.list

vanish.*: Every node ever.
