This mode does not take a sector's visibility values into account for uniform
darkening of a texture. It is more faithful to classic with respect to
fog/visibility *distances*, but may be less so as far as the "tint" of the
texture due to visibility attenuation is concerned.

That is, for every for palette (now, even ones created by the user) the last
shade is the (or rather, a color close to the) full fog color by construction.
In loadpalette(), reject a PALETTE.DAT with only one shade level.

Concretely, for all 1 <= i <= 255, make graypalookup[31][i] := graypalookup[31][0].
Also document 'fogpal' in the Lunatic doc.

Also,
- add a static assertion to engine.c
- gameexec.c: compile out an unused function in Lunatic builds

This makes the game not process as many ticks as have elapsed during the saving
afterwards.

Previously, the check was for the hard-coded sound number. This made it
impossible to change difficulty selection sounds via EVENT_SOUND.

For convenience, orientation gets bit 1 (translucency) set automatically.
Again, test/screentext.con is updated to show off this functionality (the
code there assumes that additive blending tables are loaded at blend
numbers 101 -- 132).
BUILD_LUNATIC.

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.

Hook up those from test/shadexfog.lua and some debugging ones from engine.lua.

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)
git-svn-id: https://svn.eduke32.com/eduke32@4416 1a8010ca-5511-0410-912e-c29ae57300e0
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.

The state quries the user for four values: ref. picnum, target picnum, max.
ldist and a lotag. Then, for all sprites i (of ref. picnum), for all sprites j
(of target picnum), if ldist(i,j)<=maxldist, sprite j's lotag is changed to the
provided one.
Also add lunatic/test/maputil.lua, containing a similar function but allowing
to customize the selection predicates of the ref. and target sprites, as well
as the action to carry out.

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