=========================================================================
This is the code for Moving Light Entities (Dynamic Lights)
It's basically identical to the the func_train code with out
stuff like damage and blocked code used for solid objects.
The light follows Targets and waits just like a train.
A new variable (dynlight_style) defines the type of light emitted.
Quake has only three dynamic light styles:
1 - Dimlight
2 - Brightlight
3 - Brightfield (Brightlight with 'shimmering' particles)
Dynamic Light can also be triggered, They currenty only start turned off.
