Cosa è cambiato in EDuke32, build per build

I hope I didn't bruise Lunatic too much.

While the functionality was already internally in place for gametext as one of two hacks using ROTATESPRITE_MAX (the other still used by minitext_() to align with the statusbar) we must codify a bit in the engine for safe external use. (Otherwise, ROTATESPRITE_MAX could/would theoretically increase and leave modders high and dry.) (Dev note: In G_DrawTXDigiNumZ(), ROTATESPRITE_MAX was used to bitshift the value used to calculate digit spacing for no reason I can ascertain other than to introduce rounding errors into the zoom/textscale calculations. It was never used anywhere, so I removed it.) Bonus: The scaling code for digitalnumberz and gametextz has been modified so that the spacing is no longer affected by rounding errors. Try animating the zoom value and compare how the text used to jump but now does not.

There's only one RETURN value on the C side (g_RETURN), which is also referenced from Lua. Upon entering an event, its value takes on the per-event default one, and its value when the event code finishes is passed back to the game. Independently of that, its value is always saved and restored across event calls.

In passing, fix a couple of omissions: gameactor() being passed nil's in the middle, more than one moveflag to CON *actor.

This is so that files residing in GRPs (or anywhere the engine looks for them) can be read, too.

... into a macro MFLAGS_NOCONV(m). Since it currently expands to (0), some dead code will be eliminated. Introduce a "compilation option" macro DO_MD2_MD3_CONV in mdsprite.c.

So that it doesn't result in the -t (respawn on) command line switch.

This enables ART animations to take effect on voxels in classic, voxels and models in Polymost, and models in Polymer.

The unmodified behavior is completely wrong and I don't see how any mod could ever use it.

(Modders who used an older version: Take a look at the SVN diff, the fixes can easily be applied by hand.)

Also, fix an error() call in control.lua:gamearray_file_common().

(Or '0's, but that case is handled automatically.) The resulting generated number is taken by looking at the 8 lower nibbles and interpreting them as a signed 32-bit integer. Also add some number parsing tests to test/nlcf_break.con.

Toggling whether a getactorvar for a global or per-player gamevar issues a warning or a hard error, the latter being the default. Also, make it possible to readgamevar/savegamevar per-actor gamevars and add userdefs member "idplayers" (read-only).

The first transformation makes the "control structure too long" error appear only with larger if/else cascades, though it's still possible.

Also, fix message when tiles get remapped in debugging builds.
