Dedicated bonuses fix
Fixes the issue reported here: https://mb.srb2.org/showthread.php?t=42530
What it turns out is going on is that making the game bail out in the middle of Y_StartIntermission if you're a dedicated server's host prevents the game from awarding the players bonuses in coop mode. Therefore it's not just special stage bonuses, but ANY kind of bonuses that can cause desyncs if someone loses all their lives.
This can be merged to master since it's a change only for dedicated server hosts, and should otherwise be compatible with 2.1.18.

Magnet now correctly hits nearby players and objects
SDL fixes and cleanup
Mostly cleanup tbh. I noticed a few things that bugged me when examining SDL's code recently, thought I might as well fix them up a bit.
These changes definitely does not affect netplay, so this can be merged to master just fine.

R_InitExtraColormaps fix
This fixes the `R_InitExtraColormaps` function so that it correctly realises there are no "extra colormaps" actually in SRB2's files, rather than telling you there are 6 extra colormaps on game startup (or however many WAD files total you have added).
For those who don't know what the function does, it searches for C_START/C_END markers, and if they exist, adds any lumps inbetween to a list of extra colormaps internally. They are never used by the game though, since we last supported colormaps of that kind so long ago I don't think anyone remembers when anymore (definitely more than a decade at least).
Merging to next since I don't know if this would cause any netplay issues or not tbh.
See merge request !182
This is just in case someone actually tries to dump in C_START/C_END and "add" colormaps using them, not that they would ever be used currently anyway.
Jet Jaw crash fix
Turns out not having MF_SHOOTABLE can cause the Jet Jaw to endlessly loop between the two states, until somehow LUA_CallAction inexplicably causes Z_StrDup to crash anyway (that one's a mystery to me, I'm not going to look into it right now). I tweaked A_JetJawChomp so this endless loop can't happen anymore.

obj folders fix
Partial backtrack of changes I made in !174. Apparently removing all the `.gitignore` files from `/objs`'s subfolders removed the only reason Git was keeping the folders alive (Git doesn't care about empty folders as it turns out). So now they have `.gitignore`s again, with a warning in each not to remove them.
