* commit '750bc6d6e42c55e6e96c6d14b393a73a8a819cea':
  * wp_kses allowed tags moved into own function so that we can purge it at will too. * Created safe-css control point for when we need specific styles available in wp-admin * Country problems are only logged when there is a cart. * Further code adjusts.
  * Escaping added to all getTemplate-requests. * Formatting of options. * Safe css in admin updated. * Tested changed features in admin. * (Hidden) payment fee section temporarily removed.
  Safe styles and formatting.
  Including style sheets in special template with help of wp_head(). This actually finalizes RWC-305.
  Sanitizer with both upper and lowercase.
  Escaping plugin information view with some strange effects. sanitize_key is not an option. Casting values instead of sanitizing them, when numerics.
  Major cleanup among templates.
