Allow different passwords for different purposes.

Suggestion:
And also, is it possible to set two different passwords for opguard op and deop. Because i'd like my Senior staff to be able to deop but not op.

Proposed solution:

• Add multiple config options regarding which passwords to use for what.

# By default, the same master password is used for all (since none are unique).

# If false, the master password will be used.
use-unique-op-password: false

# If false, the master password will be used.
use-unique-deop-password: false

# If false, the master password will be used.
use-unique-reload-password: false

• Update the /opguard password and /opguard reset commands to accommodate unique passwords.

Without unique passwords:

  /og password <master password>

With unique passwords:

  /og password master <master password>
  /og password op <op password>
  /og password deop <deop password>
  /og password reload <reload password>
  (with corresponding /og reset options)
