Standard Intervalometer Mode

[cshreffler]

I'd like to use the VIEW to do star trails. Even in fixed interval mode, the view doesn't allow me to select a 1 second (or lower) interval time.

Can you provide this capability? Essentially it should mimic all the behaviors of a standard external intervalometer when shooting in this mode. Ideally with the shortest possible interval between shots and with the ability to program shutter speeds longer than 30 seconds.
