Previously, the C function clipmove() returned negative values when hit a
wall (32768+wallnum) or sprite (49152+spritenum) because internally,
these values were encoded into a *signed* 16-bit integer. This made no
difference to C code using it, since it always proceeded by bit checks,
but was inconsistent with documentation on CON 'clipmove' on the wiki.
The following commands are affected too, since they use the value returned
by clipmove(): 'clipmovenoslide', 'movesprite'. Also, the value of
actor[].movflag ('htmovflag' from CON).
Also, fix 'clipmove*' in LunaCON and add lunatic/test/checknearwall.con
as an example of how to implement a being-close-to-a-wall checker as
requested in

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).

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 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.

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).

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.

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

in terms of it.

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.

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.

- 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

Known as getactor/sprite[].xpanning from CON, values are 0-255. It should be
assumed that this is only valid for wall-aligned sprites (currently, face
sprites also pan).
A test is provided in lunatic/test/animatesprites.con. It should be run in E1L2
and only with the Lunatic build.
