6.7 gravity #1
Description
as far as i know there isn't a way to tell from the sol that it's from beta 6.7, but for beta 6.7 tracks to function properly they need slightly modified gravity, so i think there will be a flag that can be applied to enable this gravity modification.
because the gravity mod is outside of the scope of base, this does mean 6.7 tracks can't be represented with only base mods. i suspect there will be a rider gravity mod in common that will be used when the 6.7 option is applied (and in that case we'll likely also switch to common's riderdef and riderstart)
