R063.1 Hotfix

Fixed an obscure bug with the help screen



SV spotter team set to 3 pop
IS2 speed to 4.8, damage to 165
SU76 barrage recharge set to 3 minutes (up from 2), now an upgrade that costs 30 MU
Fixed a bunch of SV vehicle vet mods in launcher and RGDs.
P4 IST conc barrage range set to 30 (and correctly applied to weapon), this will make it more exclusively a defensive tool
Set luft recon recharge correctly set to 6 minutes
SV Kharkhov Vets garrison heal rate reduced to 0.1 from 0.15, MU cost lowered to 10
