* Save gamedata in Y_UpdateRecordReplays(), so that you never unfairly lose out on your spoils by setting modifiedgame before the game ends.
* Always save your matchesplayed/totalplaytime increase at the successful completion of a level.
* Fix the website MS browser mapname output being incomplete.
* Hide hell maps on the website MS browser mapname output.
* (unrelated) tweak Command_Showmap_f's logic for a more accurate name.
This should hopefully alleviate the issue where textures overwrite the screen, or the screen overwrites the texture for now.
THIS IS NOT A FULL SOLUTION TO THE PROBLEM, but I highly doubt we'll ever be loading 4 billion textures at once, ever.
Specifically: removed K_StripOther calls from touching fakes: No, none of these things need to be stripped! Also, poke K_StripOther just in case it eventually becomes relevant to have it.

Unsuffixed float constants
There's an unsuffixed float constant I can't fix because the define is outside of SRB2. We could have our own copy of Pi if we really wanted.
It was brought up to me in another server that character creators might want to have unique engine sounds. While I don't want to support that ourselves, as we have consistent engines for gameplay reasons, this gives people the ability to script around it if they so choose.
Plus, it's just generally useful and I'm surprised vanilla hasn't added it, even though they have the function to stop ALL sounds on an object.
* Use CV_NOSHOWHELP as an obstacle for CV_CompleteVar (so the hidden variables don't show up and ruin our party or anything).
* Hack around the karteliminatelast thing so we don't have to hex-edit the netids, and can release with current assets (but a different executable, of course, to get the credits).
* Fix M_HandleConnectIP not saving your current position on the menu if you use it while it's empty.
