For the pagination and caret-up to return to the top,

I'm hoping if we already use fontawesome we could use the following icons:

My preference would be to use circle-caret-up to return to the top, and use angles-left, angle-left, angle-right, and angles-right for the pagination.

Should be fixed, feel free to post here if you still see issues after updating submodule and adding the latest config.toml changes.

I also adjusted what is used for the base abridge pagination.
