Nitrox

Removes a few incompatibilities and fixes a few crashes (hopefully)

- Valkyrian skies actually functions now

- Immersive portals removed due to incompatibility with VS

- Clockwork added for compat between create and VS

- Mekanism removed to keep the no cities/electricity vibe

- Updated small ships

(Any issues just let me know)

Next update will include quests if I don't need to make another quickfix
