* They're clearly not quick enough at the job, since it causes a bunch of silly race conditions.
* Instead, K_UpdateHnextList and K_CleanHnextList are in charge of removing them, which are called in the circumstances itemamount (and itemheld/eggmanheld) is changed.
* Also, tweak a few places so that trailers AND orbiters can use the same system.
Also, some minor thingies.
* Turn all the useless ```if (a) { A } else if (!a) { B }``` bullshit into ```if (a) { A } else { B }``` bullshit.
* Fix up some minor inaccuracies in the playerarrow stuff that doesn't result in creating more sprites.
* The tab and intermissions rankings...
* ...now have parity in behaviour!
* ...now properly handle player counts over 8, and no longer supports player counts over 16!
* The Item Arrow in Battle...
* No longer develops any extremely stupid bugs due to Orbinaut sprites that makes all objects in state S_INVISIBLE develop <!>'s! (Ask me about this if you're curious as to how it affected everything else too.)
While I cannot guarantee the class of glitches that allows for additional items to be thrown/dropped has been completely obliterated, this DOES prevent the class of exploits that allows for "infinite items" (really just negative quantities not completely bounds-checked for).
* Flashing Eggman-hit players.
* Fix typo with Rocket Shoe item bar, and make it extensible for potential future purposes since I was fiddling with it anyways.
* More complete playerarrow visuals for various items.
* Eggman fake (and debug) item get sounds.
* Correct a typo on Sal's part that meant flashingtics would continually grow larger and larger, slowly drifting between different clients.
* A more robust eggmanblame system.
* 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
