Add the -soft command line option which implements post-processing on
the lightmap surface to blend adjacent samples together to smooth out
hard shadow lines.

"nominlimit" is a more sensible default - people expect negative
lights to be able to subtract from minlight. The negative colors never
really worked properly and there's not really any worthwhile use for
the (that I know of).
Hopefully nobody will be too upset by these two changes to the old
behaviour.

Brush models can now self shadow without casting shadows on their
environment, using the "_shadowself" entity key.

Collect the appropriate keys from the models at load time and pass them
into the minlighting function (if > world minlight).

Similar to the skip texture handling, add miptex flags, handle
appropriately in CSGFaces and SolidBSP, then remove the surfaces before
writing out the bsp.
Lightly tested, but seems to do all the right things.

Previously, leak files would only be written for a leak in hull 2. This is
actually pretty bad because a small leak in hull 0 or 1 might not show up
in hull 2 and you would never get a leak file to chase it down.
Place a flag in the global mapdata to indicate whether we have written a
leak file or not so we only write for the first hull that leaks. Hullnum
is no longer needed as a parameter to RecursiveFillOutside, so remove
that from the fillparms struct.

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.

Some editors will work with floating point rotations, so let them keep the
precise texture alignment written to the .map file.
