* 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.
(Huge change: NO_MIDI is now a define, simply because that makes it easier for me to resolve merge conflicts if I can see the original code and the new code. Also means that people who REALLY miss MIDI can compile & fix it themselves :P)
A more detailed explanation:
* P_CheckPosition is the function which determines collisions.
* In Vanilla, collisions do not happen between players unless tailspickup is off (which it basically never is).
* Even with tailspickup off, on-spawn player collisions do not affect momentum.
* However, in kart, player collisions cause the player to get bumped.
* It would succeed at the P_CheckPosition call because players aren't *solid* solid, even though they cause bumps.
* It would fail at the K_CheckPlayersRespawnColliding call, but that would be too late, *as the player already has been bumped.*
* The player would therefore be moved to a new location, but still retain bump momentum, and the bump sound would have played for both players.
* Therefore, the obvious solution is to swap P_CheckPosition and K_CheckPlayersRespawnColliding, so that it checks for players BEFORE it performs object collisions at that spot.
* The reason we didn't see this MUCH before is that it can only ever happen in the case of ties.
I could've easily done this into master, but obviously I figure yalls'd at least like to check this first.
Also: Remove playercolor being set to the replay's color. No need to kill your settings, seeing as it makes no tangible effect on your replay (doesn't even lose colour when you die, so I don't even know...)
* Fixed the conditionals for `suicide` and `retry` commands - `suicide` is now allowed in singleplayer, and `retry` no longer checks your lives (for now).
* Disable the "traditional" level reload method (which `retry` tried to use), since it was completely broken with the other changes we've made. Mapchanges only.
* Made retries cause a mapchange, per the above.
* Disable the last source of skincolor trampling in the game - loading a level while not netgame or record attacking.
If the player count dips below what was stored on the start of the last lap, then don't do time over so that someone can't just spectate at the end of a race out of rage. Y'all are assholes :V
A couple of the extraneous ones (karma interactions, bumper stealing, lap start notifications) have been removed outright. The rest that I could think of have been changed to use CON_LogMessage, so that they still go into log.txt when rereading a fun chat session but not showing themselves in gameplay. Necessary gameplay prints, such as players being defeated or coming back in Battle, have been kept until there's a suitable replacement for them in the future.
