modify how JavaScript is used

* When disabling JavaScript, just disable it for sites (markup) so that DOM
  access and user scripts are still available even if JavaScript from external
  sources aren't loaded. This seems to be a safe way to access JavaScript
  functionality even it seems to be disabled from the perspective of web pages.
  This is being done using the setting `enable-javascript-markup` instead of
  `enable-javascript`. See:
  https://webkitgtk.org/reference/webkit2gtk/stable/property.Settings.enable-javascript-markup.html
* Make it possible to disable JavaScript by default using environment
  variables.
