The pipeline halted for some reason, so here's the smallest possible legitimate change to bump it back into action: Replacing commenting-out with `#ifdef`ing.

Somehow butchered the code cleanliness (indentation/not taking advantage of a macro I defined specifically for this) here a little by accident - tidied up.

Also, correct a minor copypaste failure in one of the I_Errors' messages.

Add a scroll bar to the addons menu. Should hopefully make the temperature gauge a little less problematic...

Means you can't have a finishline that moves up and down, but eh, thinking this might help the fallback measure disappearing

* 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...)
