* S_Init -> S_InitSfxChannels because it did mostly SFX anyway
* S_MusicPlaying, S_MusicPaused, S_MusicName, S_MusicExists new status methods
* I_MusicPlaying, I_MusicPaused
(cherry picked from commit f5f0b5e76c2fd405c8cc895dde653c5ed2652622)
* Add `kartvoterulechanges`, or "Voting Rule Changes" on the menu, to allow some user control over event frequency.
* "Never" - does what it says on the tin.
* "Sometimes" - 1/8 chance of Encore if host has unlocked it, only gametype change when buffer is full
* "Frequent" - 1/2 chance of Encore if host has unlocked it, gametype change every 5 maps
* "Always" - If host has unlocked Encore, alternates between Encore and Gametype. Otherwise, always a gametype change
* There's probably room for a setting between "Sometimes" and "Frequent", but I didn't want to overload the host with options and these were the ones that made sense.
* Better handling of buffer refreshes, to prevent two of the same map appearing next to each other in the voting unless there literally aren't that many maps.
* Mostly unrelated: Minor bugfix for Y_SetupVoteFinish, preventing music changes/random sounds playing on the You Will Join Next Race screen. (Branch-appropriate, at least.)
* Some visual ordering fixes for the item menu, plus a #define-toggleable option for the bottom right slot to be traversable for ease-of-use purposes (even if it doesn't do anything).
* Uses the in-game timer element to draw its times.
* This includes showing them time emblems-to-get!
* good night sweet prince
* Make the emblem time use the same ' and " as the normal time.
* A better representation of an Encore level, now with inverted graphics (a special remapping we can now use elsewhere whenever if we want!) and a floating Ruby!
* Decouple encore's setting from cv_kartencore on mapload. Instead, bake it into D_MapChange and related, which will only some of the time be fed by cv_kartencore's value.
* Encore mode now has a special mapheader palette setting, "encorepal", rather than using the same one as non-encore.
* HOWEVER, we should seriously address this again later, because the antialiasing DOES result in some unfortunate bullshit...
* Encoremap maces per Oni's request and Sal's suggestion
* Make unlockables have a "showing" conditionset, for when you're able to see them on the Extras screen.
* A shorter Encore ruby-pulse fade, for when encore mode is already active!
