None of this affects chat yet, that's not part of the console. I'll look at it later.

MD2 vertex/frame/triangle/etc limits checking
Fix for this bug: http://mb.srb2.org/showthread.php?t=42099
The model reading code didn't properly check if the model had too many vertices, so models with higher counts freely broke the game. This fix now stops that and prints an error message if that is the case.
However, it seems some models happily exceed other limits such as texcoords without problem (to my knowledge), so I've not bothered with checking those limits for now. Perhaps this could be a time to discuss if we need to change such limits again or not? Either way, one can easily uncomment my lines for checking texcoords/skins/triangles limits later if needed.
EDIT: I've allowed checking for triangle and frame limits too now, after some discussion.
See merge request !132
I added similar checks for the other num* but it seems some MD2s break the other limits without knowing anyway ...so I've commented these checks out for now, unless we have further discussion regarding them later on
* Space sector support complete, bounds of drowning now altered slightly.
* Knuckles climb now has symmetrical slope support for both normal and reverse gravity.
* All slope-determining topheight and bottomheight code is now identical in form.
* Camera postimages now support slopes properly.
Moved the handling of P_PlayerInSpecialSector to P_PlayerAfterThink from P_PlayerThink.
* This allows the player to get hurt on sloped lava surfaces that are moving downwards.
* Also prevents the player from standing on death pits for 1 tic.
* Prevents the player moving 1 extra tic's worth of movement of pain when hit by sector.
* Thankfully, no consequences re conveyors.
* Like, the only consequences I've found have been positive. However, this DOES need to be thoroughly investigated before it can be allowed anywhere near Next itself.
