LP1868147-Titles in carousel run together in mobile display.

This patch uses the breakpoint option available in glide.js to limit the number of images in the carousel that display.

Files for both the tpac and the bootstrap opac have been updated.

There are two new variables based on bootstrap sizing, sm_width which defaults to 3, and xs_width which defaults to 2.
If a screen's width is set between 768-992 pixels, 3 images display in the carousel,
if the width is below 768 pixels, only 2 images display in the carousel.
The reduction of images helps with titles overlapping each other.

To test:
Apply the patch to an instance of Evergreen that displays carousels.
Reduce the screen size of the browser.  Eventually the carousel will display 3 and then 2 images.
