The extended PALETTE.DAT format can now carry a trailing byte, called
'lognumalphatables'. If it is present, the engine assumes that alpha blending
tables are loaded at blend indices 1 to 1<<lognumalphatables and handles
rotatesprite's alpha and spriteext[].alpha accordingly.
The ability to save this new byte is added to engine.lua:savePaletteDat()
and the corresponding convenience functions in shadexfog.lua.
Examples test/screentext.con and test/sprite_access.con are updated for
demonstration purposes.

The overall situation is thus as follows:
- in C and from Lua, that member is called 'fogpal'
- In CON (both C-CON and LunaCON), it's 'fogpal' with 'alignto' being an alias;
'filler' wasn't available before, either.
- In m32script, it's 'fogpal' or 'alignto' ('filler' is not available any more)

That is, if that member has a nonzero value, that one is taken for the color of
the GL fog instead of (most of the time) sector[].floorpal. "Sky sectors", that
is, skyboxes or simply parallaxed floors/ceilings are *not* handled.

Also, extend the documentation for r_usenewshading a little. Specifically,
note when the different modes were introduced. BUILD_LUNATIC.

It was plainly noticeable in the editor's tile info display, for
example.

This is done by factoring out some polymer.c:polymer_getbuildmaterial() code
into polymer_eligible_for_artmapping() and using that. The one in polymer.c
can still determine to not use ART mapping on some ("rare"?) occasions, so
it's not 100% in sync.

- factor out eligible_for_tileshades()
- remove some rendmode 1 code
- move some auto vars further down

With this mode, the near distance of the linear fog is always 0, unlike being
negative with r_usenewshading 2.

For a 1680x1050 scene standing directly in front of a mirror, this increases
FPS from ~90 to ~95 for me.

One potential use is to add r_togglecomposition "0" if you don't like Aero turning on and off every time you switch between 2D mode and 32-bit 3D mode.

- Mapster32: before loading LOOKUP.DAT, set palookup[0][239]=239 to
make an identity map of the base shade table's shade 0
- Rewrite color index remapping case of makepalookup() for clarity

As opposed to the previous way, where the first fog pals was <numlookups>+1,
where <numlookups> is the first byte value of LOOKUP.DAT. This allows to
pack e.g. lookups [1 .. 25] and [30 .. <lastpal>] into LOOKUP.DAT and have fog
pals be generated at pals [26 .. 29] (i.e. the additional lookups don't
shift the fog pals, making user maps depending on these numbers not look as
intended.)

Also, error if didn't read enough data and account for TITLE and REALMS
swap between basepal number and on-disk order (sigh).

Lunatic: also, add an additional argument 'moreblends' to
engine.savePaletteDat() and document that function.
See test/shadexfog.lua for a "user-friendly" wrapper shadexfog.save() which
prints success or errors.
