Add BSP2 support to the remaining utils. Since these share the common
bspfile.[ch] files, it was more effort than is justifiable to break this
into multiple staged patches - so you just get this disgustingly big
commit instead. Here is basically what was done:
* Modify the bspdata_t struct with a union of the two bsp formats
* Modify the tools to use bsp2_t for all internal processing
* Split out the byte swapping routines for the different bsp data types
* Add simple (although verbose) code to convert bsp29 <-> bsp2
Hundreds of lines added to bspfile.c, but mostly trivial stuff. The tools
internally had little modification except to substitute the bsp2 type
names.

Transition all tools to access the BSP data via the bspdata struct instead
of the shared globals. Remove the compatibility code from bspfile which
copied the global values to/from the instanced bspdata struct.
Mostly the changes just involved passing along the bspdata struct to the
various functions which needed to reference the data. TraceLine and
MakeTNodes in light got some extra changes so that we cache the node
dplane pointer and remove the need to pass the bspdata struct to every
trace operation!

Avoids reference to global LightDataSize. Need to move writing the lit
file above the call to WriteBSPFile, since that will do the byte swapping.

Simplify the code by removing the if (colored) conditionals from the
code path. CPU cost is insignificant compared to tracing the rays.
As before, only write the lit file if colored lights are detected or
the use explicity requests it.

Since the newskip.exe tool leaves the faces in the bsp but removes
references, we will just skip over lighting such faces.

No longer update the globals in this function - make the callers do it
instead.
bspinfo no longer refers to the globals at all.

Makes minlight additive rather than just bringing low levels up to the
minimum. Not entirely identical to the bjp implementation as it seems to
treat local minlights in some strange ways, but in most cases the
behaviour should be identical.
Added missing help text for -anglescale|-anglesense parameters too.

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).

Not much point worrying about the offset of each face when it's only
per-model. This sets us up for using other per-model info...

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.

Check whether any of the entities have colored fields set and if so,
enable colored light output. Can still be overridden from the command line
if needed.
