- Removed "jellyfin" prefix from files, as they are already in a
directory named Jellyfin
- Split the former "jellyfinitem.{h,cpp}" into multiple files in the DTO
directory, one for each class. The jellyfinitem files started to
become enormous.
- Use forward declarations in headers instead of including files
wherever possible.
- Updated copyright headers
