Patch — Geocore Steam update #112364

Multiplayer finally works as intended after many months of bug hunting. Production on the multiplayer maps will now be able to advance, there are a lot listed but only a few have been worked on. I didn't see that as a good enough reason to not let people explore the layouts ofr the unfinished ones so you'll find some bare bones maps. This also frees me up to begin working on single player more, so in the next few months I should be able to release the whole first level. Added Chat (F8) Homing/Logic missiles work Old Single player restored for now Fixed Shield effect inverting on Linux Added Vulkan support
