Added flexslider library for os_slideshow #1557
New os_slideshow uses custom template instead of views.  #1557

No more views_slideshow.  Doing this the old fashioned way.  Box maintained a list of nids to use, so there was never any point in using views to build a query.

This adds three templates that can be overridden.

* os_slideshow_controls - Prints controls for slideshow.
* os_slideshow_slide - Prints a single slide
* os_slideshow_slideshow - Prints all slides and the controls.

New slideshow actually works too.  None of our options are supported yet.  Haven't figured out how to customize controls - it's either the stock flexslider controls or none at all.

Still happy with my progress.

Oh and multiple slideshows should work on the same page.  Haven't tested this yet, but made sure to change the slideshow selector to one that included the box delta.  Stored box delta's/their slider settings in Drupal.settings.
