Cosa è cambiato in EDuke32, build per build

First, it is now possible to disable the memcache (which is there to cache the texcache) by setting the new cvar 'r_memcache' to 0. Do this if you're constrained on memory or getting crashes when e.g. doing vidrestart often. Also, the memcache will disable itself (and free its storage, if it's there) the first time it fails to allocate. Fix a strcpy with identical arguments in game.c and a couple of uninitialized mem accesses related to Polymer lights.

The main feature is the addition of -mx and -mh command-line parameters to EDuke32 and Mapster32. These parameters include a con and def "module" respectively. This translates into essentially including the file from the bottom of the compiled script. I fixed the classic buggy behavior of the BROKEHYDROPLANT and REACTOR2 sprites. I also fixed a small, long-standing bug where FRAMEEFFECT1 blurs are not affected by sector floorpal. You can see one example of this by shrinking the Enforcer on the upper inside of the toppled building in E3L11: Freeway. I tweaked the Makefile so that it would automatically regenerate the keep.me files in the $(OBJ) and $(EOBJ) directories after they are deleted for cleaning. One final change is a slight positioning cleanup of both programs' --help dialog boxes.

Usage: For an ANM file <somefile>.anm/ANM, EDuke32 looks for <somefile>.ivf, which is the VP8 stream transported by an IVF container. It can be extracted from a WebM file with e.g. mkvextract tracks <filename>.webm 1:<filename>.ivf (part of Mkvtoolnix, the Matroska toolset) Libvpx is required, and the 'YUV'-->RGB conversion is implemented using a fragment shader, so it's for OpenGL modes only. Also, this commit doesn't enable the code. Unfinished: sound, aspect correction for fullscreen w/ non-square pixels, ... ? --- Make MAXNODESPERLINE in engine_priv.h actually a macro that depends on MAXYSAVES and MAXDIM instead of using the obsolete precomputed value. I think this might have been the cause for the latest patched-up overhead view crash.

* Read-only CON access to sector bunchnums by adding the labels '.ceilingbunch' and '.floorbunch' to the CON sector structure

* slightly tweaked status line, now also displaying the number of bunches * fix a couple of issues unearthed by valgrind and a TROR nextwall corruption when joining sectors

* it is now possible to paste (and have an outer red wall automatically) highlighted sectors into a sector that is extended on one side and non-sloped on the other. For this, the highlighted sectors must be in one connected component. * Make it possible to not display inner gray walls, toggled with Ctrl-Alt-A, but only when no manual grayout (Ctrl-R) is in effect. * bugfix: don't clear original TROR-nextwall link when duplicating extended highlighted sector * m32script: protect wall members relevant to TROR * save autogray (Ctrl-A) and showinnergray (see above) to mapster32.cfg

- sethighlightsector <sectnum> <on?> - updatehighlightsector - collectsectors <<array_to_collect_sectnums>> <initial_sector> <<num_collected_sectors>> <sector_filtering_state> The latter does a breadth-first search starting from an initial sector and collects nextsectors only when the filtering state, given a sectnum as RETURN input, writes a nonzero value into RETURN. As a usage example, a.m32 includes the state 'collect_teleporting_sectors', that collects all sectors containing an SE7 and highlights them afterwards. This way, it should be possible to retrofit old maps with TROR by distributing small scripts that do most of the work (right now, joining has to be done by hand, though). * corruption checker: for the 'nextwall inconsistent with nextsector' corruption, suggest an alternative fix by searching fitting nextwalls and changing the nextwall of the corrupt wall (as opposed to the nextsector). It will display with a leading '?' in the listing, and can be demanded by suffixing 'corruptcheck tryfix' with it. For example, corruptcheck tryfix 9-21 ? would fix some corruptions in Billy Boy's cranium.map without introducing drawing errors. * fix demo playback (tueidj figured this out)

* fixed subway roof interpolation; also small tweak to make this possible: http://forums.duke4.net/topic/3911-true-room-over-room/page__view__findpost__p__99099 * API change: Sect_{Set,Clear}Interpolation now takes sectnums directly

* When dragging highlighted sprites, do a setsprite() after each position update. This way, they won't end up on the wrong level * TROR support for SE 31 and 32 in-game, example provided in test map * some uncommited stuff for TROR: SE 6/14

* Make the minimum resolution possible 640x480. Sometimes you'd accidentally enter something like 'vidmode 800 60' and crashes would ensue... * fix a warning
