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

* Add a drawFill fallback for COLORMAP too.
* Correct a few index mishaps.

   - controllable strengths between 0-31 for COLORMAP lump like before
   - arbitrary colour indices in the palette via TRANSMAP lumps, with strengths 0-9
   - exposed to Lua as v.fadeScreen(color, strength)!
* Remove last vestiges of V_STATICPATCH.
