What changed in EDuke32, build by build

mapster32/build: Make AlignWalls_ not a partially broken, cryptic mess. Correctly aligns textures of any size now.

Implement tileflags member of picanm, and added support for new flag: TILEFLAGS_TRUENPOT, that allows you to enable true non-power-of-two texture support per-tile.

Enable non-power-of-two wall support in classic renderer. (Doesn't do anything yet without either a new map format, or upcoming TILEFLAGS_TRUENPOT).

Apply pogokeen's fix for hightile texture seams in polymost.

Switch to mmulti.cpp from EDuke32-OldMP repo. Loses IPv6 support, but gains stability and XP support.

Add wrapper defines to mmulti.h

Fix bad call to updatesector in G_CollectSpawnPoints that broke spawns in overlapping sectors and TROR. p->cursectnum should equal the sprite's sectnum on initial spawn.

Fix trains not moving spawn points with higher indexes than player count.

Fix player sprite disappearing and chat indicator using the wrong sprite when typing.

Re-added a check in VM_Move that probably should't have been removed.
