Streamer changes exit preset status

Browse Source 
Changing a streamer characteristic exits preset status; except for streamer length. Selection of a preset streamer when not in preset status (such as re-selecting the same preset streamer after changing one of its characteristics), sets all characteristics (including Cd and automatic checkbox); previously, the Cd and automatic checkbox were not set/reset after a manual Cd change.
