[Ugh mods]: Rebel AIs can't take SPE grenade launchers

[jaj22]

SPE grenade launcher rifles (eg. SPE_K98_GW) all have a baseWeapon of the base rifle, plus a barrel attachment. Because the arsenal converts weapons to their base weapon before adding them, this means that the grenade launcher rifles can never be unlocked and so rebel AIs can never use them.

Probably need a very specific hack to work around this.
