Tournaments ~ Limitations for Users Creating Tournaments

Staff users:

Allowed to create Tournaments.
Allowed to specify who the tournaments are open to for any tournaments.
Allowed to delete/disable any Tournaments (but they should NEVER do this unless in an emergency, such as when a tournament is created with bugs that can tear down the website altogether).
Allowed to edit any Tournaments.
Also for editing: May remove matches/players from a tournament in an emergency (such as if they detect that a player is cheating), but generally, they should NEVER add matches/players because it is unfair to other players.
Have access to details of any Tournaments.

Allowed to use tokens to create Tournaments (contact the User team to get this done, which is also considered a scope within this issue).
Allow to have partial edit control over their own tournaments; some actions shall be done by contacting staff users for assistance.
Also for editing: would not be able to remove/add matches/players to a tournament.
Allow to join tournaments that they have access to.
Are not allowed to delete/disable the tournament they created but should contact staff users to do so because the deletion of a tournament can lead to a bunch of different events that need to be handled.
Cannot access the tournaments that are not open to them.
