Unfortunately, the use of event vs 'evt' is not consistent throughout basecamp. KIT_TO uses 'evt' for evt_playback and it also used it for the topicid KIT_TO_EVT_PLBK_TLM_TOPICID. Since other topic IDs with event in the name spell it out it seemed best to at least make all of the topic IDs follow the same convention. Evt_playbk is internally consistent so it can be left alone.
