Bad permission definitions

As I've been analysing the set of permissions that are available in folio-backend-auth v0.11.0, I have found a few errors. Specifically:

• login.all includes as a sub-permission login.item.delete, but there is no such permission.
• users-bl.create includes as a sub-permission perms.users.create, but there is no such permission.
• There is a permission called login.item delete (with a space), which should presumably by login.item.delete

I don't know where these various permissions come from, so I don't know who to assign this to. I am giving it to Kurt initially, to get the ball rolling; but, Kurt, feel free to reassign if someone else should be handling this.
