/safe_action
action renders the skinmgr menu in a safe (eg. unscrewable) way using the page skin of skinmgr instead of the one of the site so if something goes wrong this action should at least give users the possibility to undo their changes

Sourcecode in SkinMgr/actions.js:
1:   function safe_action() {
2:      res.data.title = this._parent.title;
3:      res.data.list = this.renderList(this.modified);
4:      res.data.body = this.renderSkinAsString("main");
5:      this.renderSkin("page");
6:      return;
7:   }
