icons

We use icon-worker for icons.

Request to worker should be an object { route, iconList }.

route is required and may be 'main-menu', 'menu', 'page' or 'spoiler'.

iconList is not required.

If you don't send iconList to worker then only default icons for this route will be in response/

**Response from worker will be the object { route, iconList, response }.

response will be the array of objects

{
  [key]: getIcon(key)
}

Available keys:

['house', 'home', 'mag', 'search', 'err', 'error', 'warn', 'warning', 'close', 'negation', 'icon', 'cap', 'coffee', 'link', 'link-ico', 'dir', 'folder-open', 'opened', 'hw', 'mortar_board', 'study', 'pin', 'pushpin', 'exclamation', 'yes', 'question', 'open-in-new', 'page-next', 'page-previous', 'sand-watch', 'paper', 'file', 'smile', 'emotion', 'require', 'point_up', 'good', 'exelent', 'thumbsup', 'hourglass', 'wait', 'clock', 'white_check_mark', 'mail', 'speach_balloon', 'speach-balloon', 'git-ver', 'google-maps', 'slider-button', 'draw-io', 'main-menu-icon', 'expanded-main-menu-icon', 'active-main-menu-icon', 'active-expanded-main-menu-icon', 'menu-icon-image', 'menu-symbol']
