Made it possible for smoothPresetDuration, presetDurtion, and hardCutDuration (#488)

to be Double precision numbers instead of /as well as integers.
This will allow more complex transitions, such as transitions on measure
detect or 4 beat detects for example.
Forsing this to generte youtube videos, it would be good for the transitions to happen precisely when measures or stances in the music change.
