Show bigger images and other media in bubbles

[jeremyboggs]

The item bubble only shows a really small square thumbnail for items. Consider showign a bigger version of files, including playable audio and video.

The problems with making this bigger suggest perhaps having the bubble cover the timeline completely.

For this, we'll need to do some testing and experimentation with different modals and transition effects.

Do we want to make this configurable since it's a major change? If so, we'll also need:

• schema change;
• migration; and
• exhibit settings form.

If we switch to timeline.js, part of this issue is mitigated. Thumbnails will appear, but are reasonably sized. At the moment, though, there are limitations:

• only the first attached image appears
• audio files attached to the record do not appear on the slide
• videos attached do not appear on the slide

Timeline.js does have a lot of rich media capabilities, but mostly by way of pulling in video/audio/images from other services (i.e., Youtube, Vimeo, flickr, etc...). If we wish to utilize that, we would need to build in a way to attach urls for such to the record, and pass that data into the json file for the record that timeline.js consumes.

@csbailey5t Part of this issue originally was, in the HTML generated for the bubble content, I only used the Omeka helper for a square thumbnail (item_square_thumbnail() I think). We could easily just use other helpers, depending on the requirements and affordances of Timeline.js.
