Ragdollified Player Revive/Drag

Added

• downedMarkerHeight client config to set how high the revive marker floats above the body (default 0.7)

Fixed/Changed

• The revive marker is now a single icon that always faces the camera, so it no longer shows up twice or flickers
• The revive marker now floats just above the ragdoll's torso instead of up at standing head height
• Downed health now shows as vanilla hearts where the normal health bar sits, and they blink and shake like vanilla's
• The normal health bar is hidden while you're downed so the two don't overlap
• Updated to Ragdollified 1.1.5
