Basic "You are the Traitor" and "The Traitors have won" UI

[TaylorNAlbarnaz]

Summary

Currently you can only see you are a traitor by holding TAB and seeing if you have objectives, it would be better if there was an UI text on the screen showing that you are a traitor.

Also, right now blowing up the nuke just waits a few seconds and ends the round abruptly, it would be better if it showed a "The traitors have won!" UI text.

Goal

• [ ] UI for showing the client is a traitor.
• [ ] UI for knowing when the traitors have won and the round is about to end.
