New Quick Open Dialog

  - Updated list view with thumbnails, and separate file name.
  - Added a grid view which has larger icons.
  - Added toggle to filter out files from addons.
  - Store history for each opened resource type.

New Editor settings for Quick Open:
  - Startup display mode (grid or list):
      - Determined by the requested resource type.
      - Whatever was last used.
  - Toggle to filter out files from addons (for persistence).

Notes
  - The dialog is now created once in EditorNode, and globally available for other components.
  - A fixed number of result scenes are instantiated, and reused based on query.
  - Drop support for multiselect.
