Timeline blocked by Firefox when used on SSL-based sites.

[GoogleCodeExporter]

When including Simile Timeline in a site running on SSL, the timeline API is 
blocked by the browser. 

First step taken to mitigate this was to load the timeline-api.js at its SSL 
URL: <script type="text/javascript" 
src="https://api.simile-widgets.org/timeline/2.3.1/timeline-api.js?bundle=true">
</script>

Unfortunately, it breaks when timeline-api.js attempts to load additional JS 
files over http://

This cascades, and prevents the Timeline API from loading at all. 

Output from Firebug on Firefox 27:

Blocked loading mixed active content 
"http://api.simile-widgets.org/ajax/2.2.1/simile-ajax-api.js" timeli...le=true 
(line 270)
document.write("<script src='" + url + "' type='text/javascript'></script>");
