e1845c8d05 In ext. PALETTE.DAT, store log2 of last alpha table index. Handle alpha in classic.
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.

b02aa43036 Lunatic: generalize shadexfog.create_trans() further.
It now accepts a number of tables to create as 3rd arg. The function that
create_trans() takes as the 2nd argument is now being passed
(r,g,b, R,G,B, tablei, numtables).
Rewrite create_additive_trans() in terms of it.
Rename create_128_trans() -> create_alpha_trans().

caed55e9a4 Lunatic: engine.setupDebugBasePal(), auto-detect 2nd+ shadexfog.translate().
engine.setupDebugBasePal() set up the water base palette such each of the first
15 "ramps" of 16 consecutive colors has a single, "representative" color. For
example, color indices 0-15 and black, 16-31 are dark gray.
In shadexfog.lua, list remappings from LOOKUP.DAT that are expressible as
remappings of 16-tuples.

b79fa42903 Lunatic: add engine.saveLookupDat() and document, related tweaks.
- 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

37ffae149e Lunatic: rewrite shadexfog.create_128_trans to allow creating fewer tables.
It must be a power of two in [2 .. 128]. Rewrite test/sprite_access.con's
liztroop example to account for that.
Also, add function shadexfog.create_trans() which aceepts a function
(r,g,b,R,G,B) -> blended (r,g,b) and rewrite shadexfog.create_additive_trans()
in terms of it.

846fcdf31c Extend PALETTE.DAT format to allow carrying additional blending tables.
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.

330b744a1b Classic: support for multiple blending tables + Lunatic interfaces.
Currently, sprite[].filler (to be renamed) selects a blending table. If none
is installed with that index, the blending table at index 0 is taken (which is
read from PALETTE.DAT on engine startup). Thus, for now, the non-Lunatic build
will never use a custom blending table because there's no way to register one!
But the functionality is there.

13c125db02 Lunatic: add 'engine' module, currently allowing to create custom shade tables.
Available in the game and editor. Provide test/shadexfog.lua, containing a
function to creating a set of 32 shade tables corresponding to different shades
of the same fog palookup table, together with some tests and convenience
functions.

Also,
- Add gv.LUNATIC_CLIENT{,_EDUKE32,_MAPSTER32}
- Add LUNATIC_FIRST_TIME in the global env for the game
- defs_m32.lua: add reload() convenience function
- Failed attempt at recreating the base shade table. It is NOT a linear ramp
  of the base palette colors to (0,0,0). That is, it's not created by
  build/util/transpal.exe!
