Fix player mouse look

[Dennis-Nesterenko]

Currently, the players annoyingly looks at the mouse no matter where it is. This should be updated to be not as jarring.

Make mouse look more subtle by doing several things:

• The player does not look at the mouse if its too close to the player, behind the player, and if the mouse is near or on UI elements
• The head turn is much slower and more subtle. Have the head lag behind the position of the mouse.
• The head doesn't move if the mouse is moving too much.
• Add a toggle in the settings since I know that some people can find this feature annoying
• Add a delay between the mouse reaching its position and the player looking at it
• Maybe make it so the player looks in a more general direction instead of right on the mouse?

Some pointers:

• Mouse look should only activate at around 1-3 meters away from the player
• Mouse look should only activate within a cone of around 100 degrees and with a 25 degree slice directly in front of the player where look doesn't activate.
