Hard coded values needs to be made adjustable

[Whip]

Great plugin but a lot of settings are hard coded in the js file which are important to adjust to get the right look. Can you add them to the options? I tried but I'm not that good at JS. The effects array always initializes with the hard coded value of EFFECTS_DURATION even if I update the variable from options. And when the effect array is created, options have not been initialized at that point.
