Clearing old messages in the Terminal Component

[calummackervoy]

Currently messages in the terminal feed hang around until the end of the session. It would be better if only the most recent messages are loaded into view

Maybe we want to throw away the old messages, or maybe we would prefer to support storing them so that a user can view their history. Since messages are supposed to be quite common this could become a large data set to store, like a long conversation in a traditional messaging app

My preference would be to throw away old messages for now and open an issue for their possible storage
