Subject: [PATCH] ui/handler: Implement UI Handler interface class

Adds the ability to override the UI for very specific encoders in order to properly support customized and detailed UI for each encoder. This design is flexible and allows for any kind of UI generator to work, without relying on an actual object too much.
