Pwease no kicky
Don't kick Tails! Also, a movement for the WRITESINT8 to prevent modification to buf if the function bails early.
This can go into Master, right? It only matters for the host, and it's explicitly only having a major effect outside of netgames.
See merge request !201
*Add CONS_Printf messages for !netgame checks
*Arg count is checked first regardless of netgame status for both kick and ban, < 2 is checked instead of == 1 just in case these weren't called from console for some stupid reason?
*Moved Command_Kick's buffer vars to within the code that actually does kicking stuff
OpenGL slope FOF lighting fix
This fixes some issues with sloped FOFs that affect lighting in OpenGL (as in, those that cast a shadow or have a colormap). Particularly, they can do strange things to any wall textures adjacent to them, as we've noticed ourselves in levels for 2.2. =P

Polyobject seg render fix
This fixes both Software and OpenGL renderers so that polyobject segs aren't drawn if the game is drawing the actual subsectors they're from (outside the main level, where the polyobject walls were pre-spawn). They should only appear as part of the polyobject itself in-level.
This means a few glitches with polyobjects are probably fixed: for instance in Software mode, polyobject walls sometimes appear through level boundaries (and make everything above/below vanish, turning into HOM or skybox), if the BSP rendering code happens to find one of the subsectors said segs came from outside the level. I don't think anything similar happens in OpenGL, though I'm sure some unwanted typecasting is happening as a result of attempting to draw the segs. (And it fixes a crash in 2.2 anyway.)
See merge request !195
Polyobject segs should ONLY be drawn if the polyobject itself is in the polylist of a subsector being rendered. That way you won't sometimes see polyobject walls through level boundaries, if you happen to be close enough to their pre-spawn locations outside the level (or in them, if you decided to go on a noclip journey).
Ignore askinfoviams
Turns out PT_ASKINFOVIAMS is an obsolete packet type anyway, the MS doesn't send it at all. So let's just ignore it in the netcode then. (the online page just acts like a client and sends PT_ASKINFO, and is not part of the MS itself)

Netcode hotfix
Various netcode fixes are included in this branch. Most important of all of course is a fix for the Net_CloseConnection invalid node -32769 detected message thing, or rather what actually caused that to occur.
It's a merge to master since everything here should be compatible with 2.1.18: the only main changes are related to recieving packets (whether you're the host of a netgame or a client), which AFAIK shouldn't cause desyncs if you played with these fixes on a 2.1.18-hosted netgame (or hosted a netgame with the fixes and 2.1.18-using players join you).

A bunch of bugfixes about too many wads in netgames
Fixes:
* Having bunch of music WADs added and then breaching the file limit(s) through joining a server with important files added. http://mb.srb2.org/showthread.php?t=42662
* Having a bunch of music WADs added, joining a server, and then breaching the file limit(s) when the server adds a file. https://mb.srb2.org/showthread.php?t=34664
* Informing the adminplayer whenever they try to send a request addfile net command but the file limit(s) are reached.
Done into next because I might as well be 100% safe, even though this could probably work on master as well.

Missiles 'n slopes
Fixed that thing where missiles like sliding up slopes for some reason.
This isn't a 1:1 fix compared to non-slopes - missiles still like stepping up over the borders of sloped sectors and will continue going as long as they never touch that ground again, whereas they can never step up on flat ones - but this fixes the most egregrious issue.

* if you sent it to a client rather than the server, game over, your connection is closed
* if files that don't exist or are too large are requested are listed, game over, your connection is closed (they should have been checked on YOUR side beforehand, silly)
* if the server has downloading disabled anyway, ...yeah, you get the idea
Don't worry, I made sure Got_RequestFilePak cleaned up the full file request list for the node in case of failure
NiGHTS capsule color fix
This fixes the Egg/Ideya capsule from NiGHTS stages being given SKINCOLOR_RED as a color. Not really relevant for vanilla SRB2 (since it doesn't use green in the sprite), but it may be relevant for custom mods using a custom NiGHTS capsule sprite that happens to use green.

Exit your server desync fix
This branch fixes this bug: https://mb.srb2.org/showthread.php?t=41811
Here's an explanation of how this bug is actually happening:
* Pressing Enter with "Start" selected calls `D_MapChange` to make a map change command. (Note that part of it is actually delayed because it's called from a menu, but this isn't relevant to the bug)
* `D_MapChange` itself calls `SV_StartServer` to start up the server, if you're supposed to be the server player.
* Pressing Esc while starting up a server like shown in the gif causes the server to be cancelled, and go back to the title screen.
* HOWEVER, since we're still in `D_MapChange`, the map change command is made anyway.
* Since we're not in a netgame as expected, no random seed is added, and the map change command has a total size of 9 bytes (1 for the id + 8 for the actual data). This is then stored in the net command buffer. The random seed would add another 4 bytes if it WAS added, note.
* Next time you start a server, and let it work as normal, two more net commands are added: an "add player" command (size 3), and a map change command (size 13, including random seed this time). Your net command buffer now has a total size of **25** (9 + 3 + 13).
* This net command buffer is then sent as a `PT_TEXTCMD` packet to yourself.
* SRB2 recieves the `PT_TEXTCMD` you sent to yourself, and some time later, tries to run the net commands stored in it.
* The first map command is read as if it's size 13 rather than size 9 (it isn't), mistakeningly thinking a 4-byte random seed is stored (since you ARE in a netgame now). This means your buffer reads what it thinks is the next net command starting from position **[14]** in the buffer.
* Bad luck, it gets an id of **0**, which doesn't correspond with any net command!
* This message is then printed in the console:
> WARNING: Got unknown net command [14]=0 (max 25)
* The game subsequently kicks you out the server with a "desynch" message.
tl;dr The game doesn't correctly cancel the map change when you cancel the server with Esc like that. This is not a good thing.
