Feel free to reorganize as necessary.

Credits update

See merge request !231

Fix Lua panic when archiving a table element with an userdata key

Download filename trunc fix

See merge request !230

shrunk buffer from 32 to 28 so that all of "Downloading "extremely...longname.wad"" can fit on screen at once.

* fix screen to properly truncate the filename to just the real name only
* if the real name itself is too long, use ellipsis and paste in parts of the start and end of the actual name

note: I haven't actually tested if this works or compiles yet, I haven't the time right now

Zoning out

Linux limbo

See merge request !228

SOC sanitizing

See merge request !227

Console key breakfast

See merge request !226

Turns out compiling for Linux 32-bit using the Makefiles never actually defines LINUX! Apart from that, most of the existing Linux-specific code in SRB2's source code (except for tmap.s) actually uses __linux__ instead anyway

Eat unprintable keys too, since there's no reason to feed them to G_Responder anyway when the console is open

Make CON_Responder eat Ctrl+key combos that have no effect, instead of passing the key on to G_Responder

Total reorganisation of z_zone.c/h, added doxygen-compatible comments to all functions and additional regular comments where appropriate, changed purge tag macros to an enum list

Clean up z_zone.h's function protos to look more readable like m_random.h, don't name functions with "2" if not using PARANOIA or ZDEBUG

also, Z_Malloc/Calloc/Realloc are now macros of the "Align" versions, regardless of ZDEBUG or not

Fix net commands not always being freed

File loading cleanup

See merge request STJr/SRB2Internal!129

Fix SOC/Lua loading messages to display full names or even display at all (for PK3s at least), and otherwise some cleanup of existing code for the messages.

Also, I moved lua_lumploading on/offing to LUA_LoadFile.
