UI / HUD UPDATE! — Aw Heck, WAR! Steam update #339122

Changes: 1.) I reworked the HUD system that displays messages when things happen in game, so now messages wont clip through walls. 2.) Added a message that displays the game objectives when the level starts so the player has a bit better of an idea how to win. 3.) Added a warning when the VR player leaves their play-space 4.) Added a visual health bar along with the health quantity 5.) For now, I hid all game modes but Peaceful and Hardcore, after seeing some third-party gameplay, I need to redo them so when the game mode is over, it notifies you and gives you an option to restart the game so you aren't left wandering the map with no more enemies.
