Subject: Revert ALL jekyll-text-theme configuration files

I am changing the theme of the site, and need to revert these changes
to make everything work.

Revert "Add jekyll-text-theme YAML files"

This reverts commit 61b34a5f260db45575d448d766ea29c0fb273ed3.

Revert "Bring all of jekyll-text-theme _includes into site"

This reverts commit c6bf5f7c895287d2028f6024265913b59784a154.

Revert "Bring all of jekyll-text-theme assets to site"

This reverts commit 7b69c2e5975f98da09d932ba6c70bdd71b1601a7.

Remove jekyll text theme from Gemfile
