DM Swirl Alpha 07 2019 addon

This release is by no means finished version. It is an alpha release – it’s unoptimized (I don’t have framerate drops, however I haven’t tested it on other pc), unpolished, even the visuals are unfinished. I need to work on the background and some other areas (especially tunnels around flak cannon). However I wanted to show the progress and how much has been done already. I also need some feedback. All in all, I still hope you enjoy it! July notes I managed to decrease the file size (it's around 640 MB right now) without really downgrading the visuals. I made various optimizations so the performance should be much better right now. I also made some areas (especially the tunnels) in the map more spacious.
