Updates on test server (Patreon)

1. Final version of flying animation with all transition animations and fixed issues with collisions, let me know in the comments if there are still any issues with collisions and flying.

2. Region system, that loads only visible part of the map, paving the way for larger maps and switching to different maps (like entering houses or dungeons)

3. Map switching demo didn't get into the update because of last minute bug, hopefully I will be able to fix it for the next update.
