#1716: Render a placeholder image in wysiwyg.

Media used to take care of this before. If a formatter returned nothing for a wysiwyg, it would generate a placeholder image. Now the default behavior is to generate a link to the file instead. This is useless for iframes, so I had to render something. With that fixed, the rendering issue on node view fixed itself.

Fixed slideshow description typos.  #1557

Fixed text typos.

@tcheng001, I tried to fix the randomize option but it's working as far as I can tell.  It doesn't play the slides in a random order.  They'll still play 1, 2, 3, 4, 5, etc.  But the order is shuffled before the slides are added.  So which slide is 1 and which slide is 2 will vary when you load the page.

To test, create a slideshow with at least 4 slides.  Memorize their order.  Refresh the page.  Did they keep that order or get a different one?
