Small update this weekend

• Swapped the "X" crosshair (for invalid targets)  to a small dot
• Swapped the "O" crosshair (for valid targets) with a higher, thicker ring.
• Turned down the music a tad
• Added text on how to use the Calibration machine.
• Fixed colliders on player fists (the right hand was WAY off)
• Fixed spectators stats to use the full width of the screen
• Reworked the Tutorial's scripting system to avoid sequence breaking.
