Kevin Shanahan f20033fdd7 light: dynamically allocate entities and entstring
Removes the MAX_MAP_ENTITIES and MAX_MAP_ENTSTRING limitations by
counting how much space we will need before parsing/writing.

Now that I look at it, I'm not sure why we should even be re-writing
the entity string in the new bsp file, but I'll leave that behaviour
alone... for now.

Kevin Shanahan a8d8150791 light: implement the -gate option
Precalculate the distance at which lights will fade to zero brightness.
For lights with inverse falloff, use the gate value to determine the
cut-off distance.  Use this value to cull samples and avoid the ray
tracing overhead.

Hopefully not too controversially, I am going to default this to "on" with
a gate value of 0.001. Unless you have > 1000 lights contributing
fractional light values across your map, this is not going to make any
visible difference.

Kevin Shanahan f07007f8ad light: setup spotlight paramters once at load time
We were calculating these values for every light and for every surface,
which seems a little excessive... Also made the variable names a bit more
sensible - we had stored a direction vector, not the actual mangle values.
