initial_zoom: 0 is ignored

[dshapiro-whitecap]

This issue is caused by this line:

TimelineJS3/src/js/timeline/Timeline.js

Line 437 in 6a78272

if (this.options.initial_zoom) {

The if condition inappropriately bypasses setting the initial zoom to index 0 due to the falsy nature of JavaScript and should, instead, be something like:

if (this.options.initial_zoom !== undefined && this.options.initial_zoom !== null)

I am working on this.
