Cleanup admin settings js files

* Move admin.js to webpack, so that this use the bundled jquery files
  instead of the deprecated window.$ Also fixing formatting

* Remove log.js that seems to be from a time where logreader was bundled
  with server and I couldn't find an usage of it anymore

* Fix recent regression in rebuild navigation function (now not depending on
  jquery anymore and bundled by webpack).
