Update to v0.4.1

Heya! 

A small note: since the length of "Episodes" tends to increase I've decided to stop piling up "Parts" of those and simply leave version numbers. So this update is something like "Episode 5 Part 1", just named differently.

Okay, so. This update's focus is mostly on Chelsea and Aurora. It has:

• 290 static renders;
• 20 animations;
• 9 new music tracks;
• some spelling corrections and bug fixes for Episode 4.

Enjoy!
