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).

First pass at detail support as implemented in tyr-qbsp, using the PRT2
file format (hopefully nobody else already decided to use that?)
Because the "leaf" terminology is pervasive across the source, I've left
it there for now (so "leaf" usually now means "cluster") and added a few
variables with the "_real" suffix when they actually mean the real leafs
and not the clusters which vis still calls leafs. A bit disgusting, but it
actually works so I'll go through and clean up naming, etc. later.

Inspired by the implementation of Benjt Jardrup, save the current state of
the vis job to disc at regular intervals so that we can resume from that
point in case the computer needs to be rebooted/shutdown or crash/power
issues occur.

Logprint will notify the threads code that the progress meter has been
interrupted and the progress meter will re-print the next time it needs to
be updated.
Unfortunately this makes all the utils depend on the thread code, but not
a big issue.

Importing parts of this from TyrQuake - means that the base type used for
managing the bit vectors is unsigned long. Not really a performance win or
anything here, just a bit nicer to not have to cast from (byte *) to
(long *) - just adds a little extra work before writing out the compressed
data.

Make the base portal vis thread safe and run on multiple threads. Use the
common thread progress indicator code.
