What changed in EDuke32, build by build

Correctly (I hope) handle the zoom argument of rotatesprite when drawing HUD models in Polymer.

Fixes various issues with selecting: sectors and duplicating them many times in a row, sprites and then deleting some of them (also adds set union ['] and difference [;] to RSHIFT); adds the ability to move all selected sprites in the XY plane in 3d mode with SHIFT-LMB and align to the grid in an absolute fashion with CTRL.

Fix wrong interpretation of SPREXT_NOTMD that would cause it to assume the flag was set whenever any flag was set, causing the models to switch on and off in Duke Plus with Polymer.

Polymost-style HUD model support for Polymer. It properly displays all HRP HUD models as far as I can tell.

Fixes crash in 2d map drawing where sector[-1] was accessed; added commands a2xy and ah2xyz to m32script, coded 2d preview of swinging and sliding doors; added "samprate" setting to configuration, useful if the default one gives jittering/echoey audio

bugfixes; mark tiles in tile selector for later grouping (press SPACE on a tile); a.m32: convert to CRLF and add [xyz]vel query in 3d mode (Alt-KP1), also different keys for Polymer override var tweaking; some CRLF->LF in LF-only files.

don't link build utils to all the libs needed for the actual engine itself

Remove detection of sprites outside of sectors at map load and fix green sprites in Mapster32 with Polymer

added BUILD functions getclosestcol and divscale, made 2d drawing commands accept VGA-palette colors (-1 through -255) in addition to editor colors, made 2d mode show Polymer SE light outlines

added m32_autoexec.cfg execution on startup of mapster32 (like autoexec.cfg for the game); in 3d mode: shift-pgup/pgdn -> alt-pgup/pgdn for 2-sided walls

Implement 'away1' and 'away2' maphacks in Polymer.

Respect the 'notmd' maphack when deciding to draw models in Polymer.

Polymer performance improvement and some game related bug fixes. Improves Polymer framerate by about 25% in most cases and fixes problems causing Duke Caribbean doors to malfunction.

fix screwed up movement in Mapster32

Emit RPG_EXPLODE, PIPEBOMB_EXPODE and LASERTRIP_EXPLODE from the actual EXPLOSION2 sprite instead of whatever spawned EXPLOSION2, to prevent the sound from being owned by whatever sprite happens to spawn with the ID the RPG/pipebomb/whatever had before it was removed

SDL/non-Windows: external midi playing with fork/exec and signals; double initprintf internal buffers since they got too long for the --help text; warn on replacing empty tile with a hightile; fix a keypad issue in Mapster32

Final round (I hope!) of sound fixes. Should also fix the crash on exit on Windows and the REACTOR sprite size bug.

This is mostly just build fixes for USE_OPENGL=0, POLYMOST=0 and POLYMER=0. Also updated the precompiled libogg/libvorbis/libvorbisfile that are supplied for MinGW.

Fix a couple of stupid typos and remove some dead code from Mapster32

check limits in more places when drawing walls in 2d mode.

Updated synthesis script, moved some non-essential files around, updated license headers on all non-BUILDLIC files, added memory cache on top of texcache to improve load times, moved some duplicated keyboard handling stuff from winlayer/sdlayer to baselayer, fixed keypad / in Mapster32 tile selector, fixed bug where p->rotscrnang and p->look_ang never reset to 0, added support for reloading maphack based polymer lights after mode changes/savegame loads, other minor changes
