Support drawing options in scheme.

It is now necessary to enable drawing map features in the scheme file.
In the `options` field one should enable the following features in
order to have these features on the map, because they are disabled by
default:
  - `draw_nodes`,
  - `draw_buildings`,
  - `draw_trees`,
  - `draw_craters`,
  - `draw_directions`

Related to #140.
