* 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
* Objects!
* Gone is the arcane, difficult-to-remember list of random flags. Say hello to MF_DONTENCOREMAP!
* Alternatively, if the object has a skincolour applied to it, it isn't encoremapped either. (Useful for ghosts, for example.)
* Sectors!
* The autodetecting of sneaker and spring panels is now much more intelligent, and only avoids remapping the plane(s) the effect is availible upon.
* Sector special group 2 no. 15 is now "Invert Encore Remap". It inverts the above detection.
* Linedefs!
* The "Transfer Line" linedef flag can now also be used to deny Encore remappings on linedef textures.
* Right now it applies to every pixel drawn specifically belonging to that linedef, but if people decide it needs changing, we CAN make it apply to midtextures only (like linedef types 900-910).
* 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!
