v1.1.0 - Adding new Staff Hiding feature.

Some new permissions:

• truewelcomer.canSetPreference - allows the /hidewelcome command, which just gives the user the following permission.
• truewelcomer.hideUser - Hides the announcement for users with this permission.

Some new configuration:

{
  "Debug Mode": false,
  // ...
  "Hide Players with AuthLevel": false,
  "AuthLevel to Hide. 0 - Both, 1 - AuthLevel1, 2 - AuthLevel2 ": 0,
  "Hide Players With Permission": false
}

• Hide Players with AuthLevel and AuthLevel to Hide are pretty self-explanatory.
• Hide Players With Permission is as well. Just controls if the announcement should actually be hidden if the user has truewelcomer.hideUser
• If Hide Players With Permission is false, the user can run /hidewelcome. The preference will be set, but it won't be followed, and a follow-up message is sent to the user letting them know that.
