Looks like the original code biased these to one side, but the
oversampling will be more accurate if we evenly distribute the points
around the actual lightmap point.

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.

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.

Implement the two extra light attenuation formulae that were added to
Benjt Jardrup's light util (http://user.tninet.se/~xir870k/readmevis.txt).

I guess this bug has been here a long time. This was preventing us from
using all four available lightmaps in most cases. Now fixed!

No more games with save/modify/restore on the entity->lightcolor.
Could have actually caused nasty races in the multithreaded case.

Stop playing silly games with saving, modifying and restoring the global
sunlight_color. A couple of variable naming changes in lightface and use
an entity pointer instead of always indexing into the global array.

Quick release to fix the ongoing saga that is my crappy .lit coloured lighting
support. I really did test it this time...
I bumped the qbsp version as well, just to track the utils "package" version.

I really should do more testing before I embarress myself by releasing stuff
so obviously broken. Use the right pointer to align lit_filebase against.

Gah! Brown paper bag material here. Memory for the Lit data was never getting
allocated and writes were happening in no man's land off the end of the
lightdata area.
