Slideshow script for ubiquity-slideshow, global to all variations.
* Interprets parameters passed via location.hash (in #?param1=key?param2 format)
* Creates an animated slideshow inside the #slideshow element.
* Automatically loads a requested locale, based on the default slides.
* Manages slideshow controls, if requested via parameters.
Assumptions are made about the design of the html document this is inside of.
Please see slides/ubuntu/index.html for an example of this script in use.
Please include this script last, after any other scripts.
Dependencies (please load these first):
link-core/jquery.js

/* Pass parameters by creating a global SLIDESHOW_OPTIONS object, containing
any options described at <http://jquery.malsup.com/cycle/options.html>
The default callback for cycle.next also checks an extra autopause parameter,
which will pause the slideshow when it reaches the end (but doesn't stop it)
