O7 Lighting

[Lohikar]

This is a port of Outpost 7's lighting system, which is more or less Aurora's with better MZ lights & offset lighting. Lighting values have been adjusted to the new (old) format, but some were approximated so may look bad in practice.

Adds:

• Directional lighting
• Offset lighting (change origin of pixel-shifted objects to fix weird falloff)
• Adaptive updates (same callstack updates if server load permits)
• Better lighting destroy logic
• No dependency on planes
• Better color mixing
• Bidirectional Z-lighting (Z-lights + Z-bleed)

Removes:

• Darksight
• Per-atom control over lighting falloff curve
