* Add missing vars highlightflags, recommendedflags, warningflags from Kart
* V_GetStringColormap() use vanilla behavior because Kart behavior glitches for us
* V_GetStringColormap() made non-static

* Seven new text colours! Gold, Lavender, Tea-green, Steel, Pink, Teal, and Peach, all added to the menu highlights cvar.
* Revamp the saycmd colour list to take advantage of them. Peach and Purple are used the least...
* In all of the string drawers, replace colormap only when charflags changes.
* Add V_SKYMAP to dehacked.c alongside the above (oversight from when I added it yonks ago...)

* Bar of levels.
* Colourisation!
* New V_SKYMAP, which hasn't been put in dehacked lists but is otherwise valid!
* New single page statistics screen!
* V_DrawFixedPatch now works at the edge of the screen!

Ghost fixes!
* On minimaps!
* Free memory after use!
* Don't spawn in midair on slopes!

* To go with this, have the HUD fade in as the title goes away.
* After complaints, only do dogear gametype indicators on the voting screen for levels which don't match the prevailing gametype, and use thin font to intrude on the level pic less.
* Make the voting screen background a different graphic in battle.
* Improve behaviour of DrawDiag in GL.

    * Super important to allow dedicated servers to continue forever without needing to add Terminal.
    * To facilitate understanding, add gametype dog-ears to the vote screen!
    * To do the above, add V_DrawDiag! Works in GL, too!!
* Unrelated shit!
    * Fix a buffer overrun in the randmapbuffer!
    * Disable spectating in splitscreen... Not 100% sure, but in 2p battle, if you spectate, you just lose one balloon and respawn...
    * Improve all the string drawing functions' behaviour - both with being SLIGHTLY clipped by the edge of the screen, and when confronted with drawing off the base 320*200 internal area

Also made flashing not-local, again.

let's be honest, it's pretty dumb to have every single possible back colormap in memory when only one is being used at a time

(no actual SLOC changes)
