[Bf-funboard] Fake Area-Lights

[Campbell Barton]

I think the best way to do this would be to have an option in the area 
lamp under RayShadow, ShadowBuffer,- then just add the normal shadow 
buffer options under it.
You could use the samples variable to control how many lights to add. on 
the x axis. so 16 samples == 16*16 lamps.
