- rewrote dynamic lights to not use actors for the internal representation and made DynamicLight a purely scripted class.

This should be less of a drag on the playsim than having each light a separate actor. A quick check with ZDCMP2 showed that the light processing time was reduced to 1/3rd from 0.5 ms to 0.17 ms per tic.
It's also one native actor class less.
