Quick update, build mode additions and fixes

Added a few new models to the game, as well as fixed a few mesh collisions of the buildings. There was also an issue with uploading, there should be a new system that shows what the error is if it fails. I also discovered an issue with the file size for screenshots, so if you had issues uploading, it likely was due to the screenshot file being to big. This patch comes with a fix, making the screenshots lower resolution therefore lower in size, so that error in question should be fixed. However, this does mean if you already have levels saved, you will have to re-save the level to get the appropriate screenshot size for uploading. Hopefully, this patch will resolve most of the issues with uploading to Steam Workshop, feel free to reach out if there are more.
