Add meta.cpp files to optionals

[crazyirish93]

Is your enhancement related to a problem? Currently, the acre2 optional's published on the steam workshop are missing meta.cpp and mod.cpp. This means that the mods cannot be auto-downloaded through the Arma 3 launcher server browser.

Solution you'd like: Update respective optional mods so they have at least the meta.cpp file.

/// Steam Workshop item name name = "ACRE2 S.O.G. Prairie Fire Compatibility";
