Store sessions in an RB tree by name rather than a list, this is tidier and allows them to easily be shown sorted in various lists (list-sessions/choose-sessions). Keep a session index which is used in a couple of places internally but make it an ever-increasing number rather than filling in gaps with new sessions.
