bootstrap v4 breaks sizing and arrows

[pschloss]

When I use bootstrap v4 rather than v3.3.5, I'm noticing places where bootstrap-photo-gallery breaks...

• the thumbnails no long represent the entire image and instead are all the same size and contain the upper left corner of the image rather than the entire width of the image.

• the glyphicons to close and move left/right in modal mode are gone

Any ideas on a fix for this? When I use bootstrap v.3.3.5, it looks like yours, but the rest of my site is using v.4, so I'd like to stick with the more recent version.
