More Bug Fixes and Reworked difficulties

Fixed a bug where the camera modes would not update on all cameras if you clicked on the UI buttons - Increased the brightness of the graveyard map to make it a bit easier to see objects in the background - Reworked evidence spawning so that its now much easier to find evidence as it spawns on all of the cameras and it loops through the ghost’s evidence types allowing for players to get all of the evidence types much faster. Previously it randomly selected evidence to drop and would spawn the same evidence multiple times before the giving all of the evidence types to the player - Reduced some of the clutter on the house map to make it a bit easier to keep track of anomalies - Removed the randomness of the door anomalies to allow for players to learn the map more without having to adjust to the random door positions each round (elevator doors on the office map are still randomized)
