Add "- Fewer" option to Facets

[684efs3]

When using the Facets with many options, there is the "+ More" button to click to see more options. This is great!

The problem becomes when you keep clicking "+ More" and and now you just see a ton of options, with no way to reduce the number of options.

Describe the solution you'd like
I propose adding a "- Fewer" button to the right of the "+ More" button.
