default timings for scene in chaser

[giacomo]

hi,
when adding a scene to a chaser in step mode there should be already a set of default timings, same when using the Dump DMX Values,
eg. 4 sec fade in/fade out and infinite duration.
I think this would help a lot during the recording and testing of chasers, especially live with the Dump DMX, appropriate times can be set later in a second fase.
regards
