MINOR Release: Replaces all CFPB color variables with non-CFPB colors and updated deps

Changed

  to your project you will need to include the CFPB color palette and the
  Capital Framework theme overrides file. Both files can be found in the
  generator-cf repo here:
  https://github.com/cfpb/generator-cf/tree/master/app/templates/src/static/css
  Background info on the new Capital Framework color variables can be found at
  cfpb/capital-framework#115.
