The Ghost AntagHUD Feature.

Created configurations for Server Admins to be able to toggle it within default config.

Modified my previous AdminVerb that allows respawns to bypass the limitations of the restrictions while also letting the admins know if the ghost has used AntagHUD

Created restriction checks for various forms of joining the round and if administrators/hosts have restricted AntagHUD users from joining the round they will not be able to.

To Do:
Create Adminverb for toggling restrictions to also be able to toggle everyones ability to use antagHUD for a round.
Create a method for "Job Banning" users from using antagHUD.
