This feature involved a lot of refactoring in order to get working correctly. I wanted to continue using the timeline view for chats thus I used alternative styling & structure for DM event kinds. This worked create since the elements map does not care. There is some queing that has to be done to decrypt message content thus I allow viewing messages even if they haven't been decrypted yet. I think this is good for transparency since you understand what is and is not decrypted. I do think that the UX could improve, because even tho it is fast, it's flashes on new messages. I did not implement saving of latest messages. I will do this later, but this feature is big enough to merge as is: an alpha state that works. I further abstracted profile & name updating to work in a more global manner. Additionally I rewrote code that had attribute scripts to use addEventListener instead. This is needed to happen anyways for security and made the codebase easier to manage.
