Gallery thumbnail popup has alternate slideshow but shouldn't have this

[Robert Lyon]

We have a bootstrap slideshow so we don't need another one in the gallery thumbnails as part of the image popup.

We should instead use the bootstrap modal for the popups in the gallery thumbnails.

To test, before patch:

Add a gallery with square-thumbs chosen.

Display the page and click on an image in the gallery

The popup has a play button in it.

After the patch:

The popup is just a modal popup now

Part of the testing should include:

1) Putting descriptions on some of the images and turning on 'show descriptions' in the gallery block config

2) Looking at the modal popup in different layout sizes

3) Large image vs small images
