  -----------
  wxGUI: Show the world map in demolocation immediately after startup (#1070)

* Shows world countries map which is in the demolocation when in demolocation.
* Needs at least CallAfter to report errors correctly if needed.
* However, CallLater 1000 is needed for proper alignment of the map in the window
  (and with the red computational region extent).
* Tests if vector map exists.

Possible future improvements: Different colors than defaults. OnIdle instead of CallLater.
