Implemented new gravity system on the player. Brief explanation:
-player has separate gravity (might consider giving everything else custom gravity too with some gravity controller? iono mang)
-to make the player jump MORE UP increase jumpVelocity
-to make the player jump LESS FAR either increase gravity or decrease movementSpeed

i like the values:
movementSpeed=10
jumpVelocity=20
gravity=45
Replaced deprecated function in Reticule with new one. Also added new functionality so you can move the reticule nearer/further away from the camera in the inspector.
